How to Choose the Best Pet Food? A Professional Guide from Nutrition and Ingredients to OEM/ODM Manufacturing Models

I. Introduction

The modern pet food market is developing rapidly, with far more choices than in the past. From the most common dry food, to highly palatable wet food, and even premium raw-style pet food products, brands, ingredients, and nutritional compositions are becoming increasingly diverse. However, choosing the right, suitable pet food for your pet is not only about nutritional intake – it also affects body condition, immunity, disease prevention, and even lifespan. For pet supplies wholesalers, pet food brands, entrepreneurs, and pet supplies suppliers, having an in-depth understanding of different pet food types and how to select them helps build a stronger product line, increase market competitiveness, and avoid many common pet food purchasing mistakes.

This article will, with a clear structure, help you understand:

• What types of pet food are there?

• How to choose the most suitable pet food formula for your pet?

• What are the common mistakes when buying pet food?

• Want to make pet food: should you produce it yourself or look for a professional OEM/ODM manufacturer?
   

 

II. What Types of Pet Food Are There?

1. Dry Food

Dry food is the most common and convenient form of pet food. It is usually made by mixing meat meal, grains, legumes, fats, and nutritional supplements and then processing them through high-temperature extrusion. Its biggest advantages are high shelf stability, relatively low cost, easy storage, and the ability of the kibble hardness to help reduce tartar build-up. The nutritional ratio of dry food is stable, making it suitable for long-term feeding and for owners who want an easy way to manage their pets’ diet. However, some dry pet foods may contain higher levels of carbohydrates, or lose some nutrients due to high-temperature processing. Therefore, when choosing pet food, you need to pay particular attention to the protein source and the overall formula quality.

Most Common and Easy to Store

• Dry food contains only 8–12% moisture, making it less likely to breed bacteria and mold, and it will not spoil as quickly at room temperature as wet food. It is the most typical mainstream pet food type.

• After opening, as long as you avoid humidity, it can be stored for several weeks to months without refrigeration or freezing, which is very friendly for stocking daily pet food.

• In high-humidity regions such as Taiwan, Hong Kong, and Southeast Asia, dry food is less likely to go rancid than wet food, making it a very practical everyday pet food option.

• It is also suitable for use in automatic feeders; it produces little dust and will not clog the mechanism, which is especially convenient for households that use dry pet food long-term.

Stable Price, Suitable for Bulk Purchasing

• The raw material and processing costs of pet food are lower than those of canned food, raw food, or freeze-dried products.

• Factory production efficiency is high, allowing large quantities of pet food to be made at once, which stabilizes the price.

• This is especially suitable for multi-cat households, multi-dog households, boarding facilities, breeders, and rescue organizations that need to stock pet food long-term.

• If wholesalers produce OEM dry food, they can also quickly expand their pet food SKUs, achieving excellent cost-effectiveness.

More Helpful for Chewing Training and Dental Health

• Dry pet food kibble provides hardness and friction, which helps slow the formation of tartar.

• Many brands design special kibble shapes (such as cross-shaped, hexagonal, S-shaped) to enhance the dental cleaning effect of pet food.

• For puppies and dogs that love to chew, dry food can satisfy their chewing needs and is a pet food choice that combines functionality.

It does not replace toothbrushing, but compared with wet food, it is less likely to cause tartar build-up and is a more dental-friendly form of pet food.

Other Extended Features

• Pet food formulas can be highly customized: high-protein, hypoallergenic, grain-free, digestive care, coat and skin care, joint support, weight control, and more.

• Palatability can be adjusted through oil spraying and meat meal ratios, allowing pet food to better match different pets’ preferences.

• Food safety is stable; high-temperature extrusion can effectively reduce the risk of Salmonella and other pathogens, making it a relatively safe pet food type.

2. Wet Food

Wet food is usually based on meat, broth, or meat paste, with a moisture content of 70–85%. It is suitable for pets that need additional water, have kidney disease, urinary tract disease, or weaker teeth. Because its aroma and texture are closer to natural food, most pets accept it very well and it is highly palatable. Wet pet food retains nutrients relatively well, but has a shorter shelf life, must be refrigerated after opening, and usually costs more than dry food. If feeding only wet pet food, it is important to ensure that the diet meets complete and balanced nutritional standards.

High Moisture Content and Great Palatability

• Moisture content can reach 70–85%, very close to natural fresh ingredients – ideal as a “hydration source” within pet food.

• Strong aroma makes it more attractive to picky eaters or pets with poor appetite; many pet food brands position wet food as an “appetite booster.”

• This is especially important for cats: as they naturally drink little water, pairing with wet pet food effectively increases daily water intake and reduces kidney burden.

• For senior pets, those with poor dental condition, or those in post-surgery recovery, wet food is often the best pet food option.

Highly Palatable and Easy to Digest

• Ingredients are mostly presented as chunks of meat, meat paste, or broth. The soft texture requires little chewing, making it a more digestion-friendly pet food form.

• It is more suitable for kittens, puppies, and senior cats and dogs whose digestive capabilities are weaker.

• Many brands create special wet pet food formulas for sensitive digestion (such as easily digestible proteins and prebiotics).

Higher Cost and Stricter Storage Requirements

• Production cost is higher: wet pet food requires high-temperature sterilization plus metal cans or foil pouches, often costing several times more than dry food.

• After opening, it spoils easily, must be refrigerated, and should be consumed within a short time.

• Mass-imported wet pet food is subject to transportation, cold-chain, and storage constraints, creating higher cost pressure for wholesalers.

Other Extended Features

• High nutritional density, suitable for pets that need rapid energy replenishment – can be designed as functional pet food.

• Can be mixed with dry food (“mixed feeding”), giving pet food more layers while increasing cats’ water intake and overall willingness to eat.

• Suitable as trial-taste food, for hiding medicine, or as an appetite-enhancing supplementary pet food.

3. Raw-Style Pet Food

Raw-style pet food emphasizes a diet close to animals’ original feeding patterns. It is usually composed of fresh meat, bones, organs, and vegetables/fruits in specific ratios, and can be presented as frozen raw meat, freeze-dried (freeze-dried) or air-dried forms. Its advantages include more complete meat nutrition, high absorption rate, and transparent, natural ingredients. Many owners believe this type of pet food can improve skin and coat condition, increase vitality, and reduce allergic reactions. However, raw food requires particular attention to food safety risks, such as bacterial contamination (Salmonella, Listeria), parasites, and hygiene during handling. For cats and dogs, if the nutritional ratio is not correctly adjusted (such as calcium-phosphorus balance), long-term health risks may occur. Therefore, when choosing raw-style pet food, you must ensure it is produced by professional factories and that the formula has undergone complete nutritional calculation, rather than mixing ingredients yourself.

Nutritional Ratios Close to Natural Diets

• Uses real meat cuts, organs, bones, vegetables, berries, and other natural ingredients to create high-meat raw-style pet food.

• Suitable for owners who emphasize biologically appropriate diets and are willing to invest more in pet food.

• Most raw-style pet foods have protein contents of 35–50% or more, which is very beneficial for highly active dogs and cats.

Processing Technologies that Preserve Nutrition (Air-Drying, Freeze-Drying)

Freeze-Drying

• Raw-style pet food is frozen at –40°C and then vacuum-dried.

• 90–97% of the nutrients are comparable to fresh meat.

• Key amino acids and enzymes are preserved, making this a common technique for high-end pet food.

Air-Drying / Low-Temperature Drying

• Low-temperature drying of pet food.

• Strong flavor and extremely high palatability.

• Texture closer to jerky or whole meat pieces.

These processes preserve natural nutritional value better than extruded dry food and are commonly used in high-end pet food.

High Unit Price and Stricter Ingredient Requirements

• Using large amounts of real meat is costly, so raw-style pet food naturally has a higher price point.

• Stricter requirements on ingredient sources (such as human-grade meat, grass-fed beef).

• In the production process, stricter control over microorganisms (Salmonella, Listeria) is required, and the equipment requirements for factories are higher, making this a high-barrier pet food category.

Suitable for Owners Pursuing High-Quality Diets

This type of food is especially suitable for:

Cats and dog breeds that need a more meat-based diet
Pets that are food-sensitive and need hypoallergenic diets
Owners who are willing to invest more in premium pet food choices
Those who prefer pet food diets that are grain-free, starch-free, and free from artificial additives

Raw-style pet food is also often used as:

• Training rewards pet food

• A supplement to complete-and-balanced canned food

• A topper on dry food to increase palatability

 

III. How to Choose High-Quality Pet Food?

Choosing pet food is not something that can be decided simply by the brand or price – you need to approach it from two main dimensions: “your pet’s needs” and “product quality.” Below, we will provide a comprehensive pet food selection guide from three perspectives: the animal’s own condition, ingredients and nutritional labeling, and supplier/factory capabilities.

1. Choosing Based on Pet Characteristics (Age, Breed, Weight, Health Condition)

Pets at different life stages, with different physical characteristics, breeds, and lifestyles, have different nutritional needs. These differences directly affect which pet food formula you should choose.

Key Points by Age (Puppy/Kitten, Adult, Senior)

Choosing by Breed

Choosing by Weight and Lifestyle

Choosing by Health Condition (Very Important)

2. Reading the Ingredient List and Nutritional Label

The ingredient list is the soul of pet food quality. Only by clearly understanding the ingredients and nutritional label can you know whether a pet food is truly suitable for your pet.

Key Points for Cat Food

Cats are classic “obligate carnivores,” so when choosing cat pet food, the most important thing is to check whether the proportion of animal protein is sufficient – the higher the animal protein, the more it meets cats’ natural physiological needs. Conversely, if the proportion of plant protein is too high, it not only has lower absorption rates but may also increase the burden on the urinary tract and kidneys. Another essential nutrient is taurine, because cats cannot synthesize it themselves but rely on it to maintain satiety, heart function, and retinal health. In addition, Omega-3 (DHA, EPA) helps improve skin and coat condition, reduce inflammation and allergic reactions, and is very important. Finally, adequate dietary fiber can promote intestinal motility and help expel hairballs; it is an indispensable nutritional component for maintaining long-term gastrointestinal health.

Animal Protein Content

• The higher the animal protein content, the more it matches cats’ physiological needs and the more crucial it is in assessing the quality of cat pet food.

• Excessive plant protein can increase the burden on the urinary tract and kidneys.

Taurine

• Cats cannot synthesize taurine themselves; it is an essential nutrient.

• Satiety, heart function, and retinal health all depend on taurine, and high-quality pet food formulas will clearly indicate its content.

Omega-3 (DHA/EPA)

• Supports skin and coat health.

• Reduces inflammation and improves allergies.

Fiber (for Hairball Management)

• Adequate fiber promotes intestinal motility and hairball passage – this is a must-have formula consideration in long-haired cat pet food.

Key Points for Dog Food

Dogs are omnivorous-leaning animals, so their daily pet food should be built around “balance.” Protein is essential for maintaining muscle mass and immune function; fat is the primary energy source for dogs, and the higher their activity level, the more fat they need to support stamina and exercise requirements. In addition, adequate dietary fiber helps maintain gastrointestinal motility and digestive health, while essential fatty acids such as Omega-3 and Omega-6 play important roles in skin, coat, and overall immune health. Only by considering all these nutrients can you provide a truly balanced pet food diet for dogs.

• Protein: maintains muscles and immunity.

• Fat: main energy source; higher activity means higher fat needs.

• Fiber: maintains gastrointestinal health.

• Essential fatty acids (Omega-3, Omega-6).

Small Animal Food (e.g., Guinea Pigs, Rabbits)

Guinea pigs cannot synthesize vitamin C by themselves, so their daily pet food must provide additional vitamin C. Otherwise, they are prone to deficiency symptoms that affect immunity and joint health. As typical herbivores, guinea pigs also need high-fiber pet food formulas and enough hay to maintain gastrointestinal motility, tooth wear, and overall digestive function. These two nutritional requirements are central to their daily care and must not be overlooked.

Ingredients to Avoid and Common Misconceptions

Unnamed meat meal (e.g., “meat meal” without specifying animal source)

Excessive fillers (too much corn flour, wheat flour)

Artificial colorants (unrelated to nutrition)

Artificial flavors (attractive but with no nutritional value)

A truly good pet food formula is:

•  Clear ingredient sourcing
•  High proportion of animal protein
•  No reliance on artificial additives

3. Choosing Qualified Pet Food Suppliers

Besides looking at the product itself, choosing a reliable pet food factory and supplier is also key to ensuring quality.

Checking International Standards and Food Safety Regulations

A high-quality pet food factory should have:

• SGS: Third-party testing and certification

• ISO 22000: Food safety management

• HACCP: Hazard Analysis and Critical Control Points

• FDA registration (necessary for exporting to the U.S.)

• AAFCO: U.S. feeding standards (meeting pet food nutritional requirements)

• BRC / IFS (high standards in the EU)

Transparency of Ingredient Sourcing

A quality pet food supplier will:

• Specify the animal protein source (e.g., “chicken meal” vs “poultry meal”)

• Clearly explain country of origin, supplier, and batch traceability

• Avoid using meat meal from unknown sources (rendered by-products)

The higher the transparency, the more reliable the pet food quality.

Clear Formula Labeling

• Are crude protein, crude fat, crude fiber, ash content, and calcium-phosphorus ratio clearly labeled?

• Is there a complete list of additives?

• Are there clear warnings for common allergens in dogs and cats (such as chicken, gluten)?

Additional Key Factors for B2B Purchasing (Important for OEM/ODM)

Supply stability: Can they ensure long-term pet food supply?
Production capacity: Can they scale production? Can they handle peak seasons?
MOQ (minimum order quantity): Is it suitable for new brands or large-scale brands?
Lead time: How long until shipment? Is there flexible scheduling?
Quality control capability: Do they have QC/QA, sample retention, and COA testing?
Can they provide pet food OEM/ODM services: including formula development, packaging design, and brand customization?

 

IV. Common Mistakes When Choosing Pet Food

1. Not Adjusting Food According to Pet’s Age

When choosing pet food, one of the most common basic mistakes owners make is failing to adjust formulas according to the pet’s age. Metabolic needs differ greatly at each life stage: puppies and kittens need high protein, high energy, and DHA to support brain development; adult cats and dogs focus on maintaining body condition, and energy levels should not be too high; senior cats and dogs have increased kidney and joint burden and usually need lower-calorie diets plus additional nutritional supplements. If you do not choose according to age – for example, allowing puppies to eat adult dog food – it may lead to insufficient growth or digestive burden; senior cats eating kitten food can further increase kidney stress. The most correct approach is to choose pet food based on AAFCO/NRC life stage indicators and to adjust the diet every 6–12 months according to changes in weight and metabolism.

2. Not Adjusting Diet After Illness (Not Supporting Disease Management)

Many pets’ diets remain unchanged after they become ill. Conditions such as kidney disease, sensitive digestion, obesity, and skin allergies all require veterinary advice combined with specific nutritional directions. Pets with kidney disease need low phosphorus, low protein, low sodium, and as much water intake as possible; digestive sensitivity is better supported by easily digestible formulas or hydrolyzed proteins combined with prebiotics; obese dogs and cats need low-fat, low-calorie diets with higher fiber to increase satiety; pets with skin allergies often need single-animal-protein formulas such as salmon, duck, or hydrolyzed protein. Many owners think “just stick with the original pet food,” which slows recovery. Adjusting pet food after illness should last at least 2–4 weeks to monitor effects – this is the core of dietary management.

3. Blindly Chasing Expensive, Trendy, or “Nice-Looking Ingredient Lists”

Some owners blindly pursue costly pet foods or those with so-called “premium ingredients,” such as cranberry, blueberry, salmon oil, or chia seeds, even though the actual added amount is minimal and may not significantly improve nutrition. Some believe the more expensive the better, or the more “fancy” the ingredient list, the more nutritious the food. In reality, what truly matters is whether the nutritional analysis meets “complete and balanced” standards, and how the pet responds after eating: whether the coat is shiny, stools are normal, and body condition is maintained. Nutrient absorption and formula integrity are always more important than a good-looking ingredient list.

4. Only Looking at the Brand Without Checking Ingredient Source and Processing (Ignoring Supply Chain Transparency)

Brand reputation is important, but what truly determines pet food quality is the supply chain behind it. Many international brands actually use OEM factories for production, so the key factors are ingredient traceability, batch testing, process control, compliance with HACCP / ISO / SGS / AAFCO, and whether COAs or batch records can be provided. Even the most beautiful packaging cannot guarantee ingredient safety. When choosing pet food, you should prioritize brands with transparent supply chains, clear labeling, and traceability.

5. Failing to Choose Pet Food According to Individual “Constitution” and “Lifestyle”

Ignoring individual differences and choosing food solely based on brand or price is another common mistake. Activity level, coat type, skin condition, neuter status, and tendency for soft stools all affect nutritional needs. For example, indoor cats that eat high-calorie pet food are very likely to become overweight; long-haired cats lacking Omega-3 and Omega-6 will have dry coats and severe shedding. The ideal approach is to observe stool quality, energy levels, coat condition, and other indicators, then choose pet food formulas that match the pet’s lifestyle. For special constitutions, it is recommended to consult a veterinarian.

6. Switching Food Too Quickly – Causing Diarrhea and Soft Stools

Switching pet food too quickly often causes diarrhea or soft stools. The correct transition process should start with 25% of the new food in days 1–3, then gradually increase to 50%, 75%, and finally completely switch over after day 10. Dogs and cats with sensitive digestion may even need a 14-day or longer transition period. “Changing everything at once” is one of the main reasons for gastrointestinal issues.

7. Thinking “One Food for a Lifetime” Is Enough

Nutritional requirements change with age, body condition, seasons, activity level, and health status. If pet food is not adjusted in the long term, it can easily lead to obesity, nutritional imbalance, poor coat quality, or gastrointestinal problems. It is recommended to carry out a body condition check every 6–12 months and discuss with your veterinarian whether dietary adjustments are needed.

 

V. Pet Food: In-House Production or OEM/ODM?

The biggest advantage of producing pet food in-house is that the brand can fully control the pet food formula, costs, and production process, adjusting everything from ingredient ratios to final texture according to its own philosophy. In-house production is highly flexible, allowing small-batch market testing and rapid product repositioning. For companies pursuing unique differentiation or wanting to build core proprietary know-how, this is a very attractive option. However, in-house pet food production also requires substantial investment, including factory infrastructure, drying equipment, sterilization technology, and quality control systems. Initial investment can easily reach into the millions or tens of millions (local currency). More importantly, all food safety risks must be borne internally – from nutritionists, veterinarians, and R&D staff to testing procedures, everything must be fully in place. Without large-scale production to spread fixed costs, the unit production cost per product will be significantly higher.

In contrast, commissioning OEM/ODM can dramatically reduce initial investment costs. You do not need to build a pet food factory yourself and can leverage existing equipment, mature technology, and professional teams to enter the market. Many OEM manufacturers also provide ready-made pet food formulas, allowing brands to quickly launch new products, or adjust them according to custom requirements. Professional factories are usually well versed in regulations, labeling, and quality control processes, helping brands avoid compliance pitfalls. This is especially suitable for start-up brands or those wishing to accelerate time-to-market. However, OEM/ODM is not without limitations: the most common challenges include minimum order quantities (MOQ) defined by the factory, which can make small-batch testing difficult; the higher the degree of customization, the longer the lead times and the higher the required order volume.

How to Decide? (Guiding the Reader)

You can ask yourself three questions:

1. Does my brand require a high degree of custom pet food formulation?

2. Do I have the capacity to handle regulations, testing, and food safety responsibilities?

3. How quickly do I want my pet food products to reach the market?

If you are unsure, it is recommended to start by using a pet food OEM/ODM partner to test the market and then consider building your own production lines later.
