OEM Development Guide for Pet Food and Pet Treats

Japan's pet food market continues to grow steadily, with premiumization and the natural/organic trend driving major shifts. Against a backdrop of declining birth rates and increasing single-person households, more pet owners treat their pets as "family members" and demand human-equivalent quality in pet food.

The Rise of Human-Grade Pet Food

The most prominent trend in the pet food market is "human grade"—pet food made from ingredients that meet human food quality standards. While conventional pet food often used by-products and off-spec materials from human food manufacturing, rising owner awareness has shifted demand toward products sourced to the same quality standards as human food.

• Ingredient transparency: There is a trend toward clearly listing ingredients like "chicken" or "beef" rather than vague terms like "meat meal" or "poultry meal." Since pet owners closely scrutinize ingredient labels, transparency is the key to building trust.
• Demand for domestically sourced ingredients: Driven by safety concerns, demand for pet food using ingredients sourced in Japan is rising. Products specifying domestic chicken, domestic vegetables, or domestic fish as their origin can serve as strong differentiators.
• Additive-free formulations: Products marketed as "additive-free"—without synthetic preservatives, colorings, or fragrances—are increasing. The mainstream approach uses natural antioxidants such as vitamin E and rosemary extract.

Grain-Free and Allergy-Friendly Products

Grain-free pet food, which excludes grains, is another popular category. Formulations that avoid wheat, corn, and soy are supported by pet owners concerned about food allergies in dogs and cats. Alternative carbohydrate sources include sweet potato, peas, and tapioca. Single-protein-source products (venison only, fish only, etc.) designed for allergy management are also seeing growing demand.

Opportunities for New Entrants

While major manufacturers hold large market shares in pet food, new brands are finding success in niche and premium segments. Strategies leveraging social media and D2C (direct-to-consumer) models to differentiate through brand storytelling and ingredient sourcing are proving effective. An increasing number of businesses that operate pet shops, grooming salons, veterinary clinics, or pet hotels are also launching their own pet food brands.

When manufacturing and selling pet food, understanding and complying with Japan's "Act on Ensuring the Safety of Pet Food" (commonly known as the Pet Food Safety Act) is essential. Enacted in 2009, this law was established to ensure the safety of pet food for dogs and cats.

Overview of the Pet Food Safety Act

The Pet Food Safety Act applies to pet food for dogs and cats (other pet species are not covered). Key regulations include:

• Business notification: Pet food manufacturers and importers must file a notification with the Minister of Agriculture, Forestry and Fisheries and the Minister of the Environment before commencing operations. When outsourcing production to an OEM manufacturer, the manufacturer handles their own notification, but notification obligations for selling under your own brand should be confirmed in advance.
• Composition standards and manufacturing standards: Maximum allowable levels are set for hazardous substances in pet food, including aflatoxin B1 (mycotoxin), pesticides (ethoxyquin, BHA, BHT, etc.), and heavy metals (arsenic, lead).
• Labeling standards: Pet food packages must display the product name, best-before date, ingredient list, country of origin, and the business operator's name and address.
• Record-keeping requirements: Records of manufacturing, importing, and sales must be maintained in ledgers and retained for a specified period.

Labeling Standards in Detail

Labeling standards under the Pet Food Safety Act follow different rules than Japan's Food Labeling Act for human food.

• Product name: State the product name (e.g., "Dog Food," "Cat Treat").
• Best-before date: Display as year-month-day or year-month.
• Ingredient list: List ingredients in descending order of quantity. Additives must also be disclosed.
• Country of origin: State the country where final processing occurred. Products manufactured by an OEM in Japan can be labeled "Japan."
• Business operator name and address: Display information of the manufacturer or seller.

Types and Classification of Pet Food

Pet food is classified into several types based on use and purpose. The standards and labeling requirements differ depending on which type of product you develop.

• Complete and balanced food: Food that provides all necessary nutrition when fed with water alone. Must meet the nutritional standards of AAFCO (Association of American Feed Control Officials) or FEDIAF (European Pet Food Industry Federation).
• Treats/snacks: Given for training, rewards, or bonding. The guideline is no more than 20% of daily caloric needs.
• Veterinary/therapeutic diets: Nutritionally formulated to address specific health conditions. Used under veterinary guidance.
• Complementary food (side dishes): Side-dish-type food intended to be fed alongside complete and balanced food.

The most critical factors determining pet food quality are ingredient selection and nutritional balance design. Especially when developing complete and balanced food, compliance with international nutritional standards is required.

Key Points for Ingredient Selection

Pet food ingredient selection must balance safety, nutritional value, and palatability.

• Primary protein sources: Chicken, beef, pork, venison, horse meat, salmon, white fish, eggs, etc. For both dogs and cats, protein is the most important nutrient, and the market trend is to use high-quality animal protein as the primary ingredient. Single-protein formulations also address allergy concerns.
• Carbohydrate sources: White rice, brown rice, barley, sweet potato, potato, tapioca, etc. For grain-free products, tubers and legumes are used. Dogs and cats have different carbohydrate requirements—cats need a higher ratio of protein and fat compared to dogs.
• Fat sources: Chicken fat, salmon oil, flaxseed oil, coconut oil, etc. Omega-3 fatty acids (EPA and DHA) contribute to skin and coat health, and more brands are actively incorporating them.
• Functional ingredients: Probiotics, oligosaccharides (gut health), glucosamine and chondroitin (joint care), lutein (eye health)—incorporating health-functional ingredients enables product differentiation.

What Are AAFCO/FEDIAF Standards?

AAFCO (Association of American Feed Control Officials) and FEDIAF (European Pet Food Industry Federation) are international bodies that establish nutritional standards for pet food. In Japan, the Pet Food Fair Trade Council has adopted nutritional standards based on AAFCO guidelines.

• Growth stage vs. adult maintenance: Nutritional requirements vary by life stage. Puppies and kittens during the growth stage need higher levels of protein, calcium, and other nutrients. AAFCO provides separate standards for growth and adult maintenance.
• Minimum and maximum values: Minimum values (and maximum values for some nutrients) are established for approximately 40 nutrients including protein, fat, vitamins, and minerals. Meeting these standards allows a product to be labeled "complete and balanced food."
• Feeding trials: AAFCO compliance can be verified either through formulation calculation and laboratory analysis, or through actual feeding trials that monitor pet health over a defined period.

Allergen Management

Pet food allergies are a major concern for owners, and demand for allergen-friendly products is very high.

• Novel proteins: Venison, kangaroo, horse meat, and insect protein are less commonly found in standard pet food and are suitable for pets with allergies to conventional protein sources.
• Hydrolyzed proteins: Proteins broken down into small fragments by enzymes are less likely to trigger allergic reactions. Widely used in veterinary therapeutic diets.
• Cross-contamination control on production lines: When making allergen-friendly claims, attention to cross-contamination with other ingredients on the production line is necessary. Verify the OEM manufacturer's production line management practices.

Pet food and pet treats come in a diverse range of manufacturing formats. The optimal format must be chosen based on the target pet species, size, product concept, and sales channels. Understanding the characteristics and ideal applications of each format is essential.

Dry Food (Kibble)

The most common pet food format, accounting for the majority of the market. Manufactured using an extruder that shapes and puffs the product under high temperature and pressure, then dries it.

• Advantages: Long shelf life at room temperature (1–2 years), low logistics costs, low per-meal cost, and often said to support dental health.
• Disadvantages: Palatability (eagerness to eat) tends to be lower than wet food; some nutrient loss may occur during high-temperature processing.
• Lot size guidance: Due to the minimum operating volume of extruders, minimum lot sizes are relatively large—typically several hundred kilograms.

Wet Food (Cans and Pouches)

Products filled into cans or retort pouches and heat-sterilized. High moisture content (70–80%) and very high palatability are the hallmarks.

• Advantages: Excellent palatability, contributes to hydration, well-suited for senior pets with reduced appetite.
• Disadvantages: Requires refrigeration after opening, higher logistics costs due to weight, higher per-meal cost.
• Ideal products: Premium food, therapeutic diets, senior pet food, complementary food (side-dish type).

Freeze-Dried

A method where food is frozen and then vacuum-dried, resulting in minimal loss of nutrients and flavor—an increasingly popular production method.

• Advantages: High nutritional value, excellent flavor retention, ultra-lightweight for low shipping costs, room-temperature storage.
• Disadvantages: High manufacturing cost, resulting in high retail price.
• Ideal products: Premium treats, food toppers, training treats.

Jerky and Dried Treats

Treats made by drying meat or fish—a mainstay of the pet treat market. The simple ingredients and processing make it easy to market as "just the real ingredient."

• Advantages: Simple ingredient list inspires confidence, chewy texture supports dental health, room-temperature storage.
• Disadvantages: Drying is time-intensive, and raw ingredient quality directly impacts flavor.
• Ideal products: Reward treats, training treats, dental care treats.

Product Design Advice

For first-time pet food OEM developers, starting with the treat (snack) category is recommended. Complete and balanced food requires compliance with AAFCO standards and involves higher development complexity, whereas treats can start with relatively simple formulations, and small-lot OEM manufacturers are easier to find. Building a track record with jerky or freeze-dried treats and growing brand recognition before expanding into complete food is an effective phased approach.

To succeed in pet food OEM development, selecting an OEM manufacturer that aligns with your product concept is crucial. Pet food OEM specialists possess different expertise and equipment than human food OEM manufacturers.

OEM Manufacturer Selection Checklist

• Manufacturing format capabilities: Verify that the manufacturer has the equipment for your target format—dry food, wet food, freeze-dried, jerky, etc. Few manufacturers cover all formats, so consider working with different manufacturers for different products.
• Quality control systems: Check for HACCP certification, incoming ingredient inspection procedures, and product safety testing (microbiological testing, heavy metal analysis, etc.). Compliance testing systems for the composition standards under Japan's Pet Food Safety Act are also a key checkpoint.
• Human-grade capability: If marketing products as human-grade, you need a manufacturer that can produce under hygiene standards equivalent to human food. Ideally, choose a manufacturer that holds human food production permits and applies those standards to pet food production as well.
• Minimum lot sizes and pricing: Minimum lot sizes vary significantly by manufacturer and format. Dry food typically starts at several hundred kilograms; wet food depends on retort sterilizer batch sizes; jerky may start from as little as a few tens of kilograms. Confirm in advance.
• Nutritional design support: For complete and balanced food, AAFCO/FEDIAF-compliant formulation expertise is required. Manufacturers with staff trained in pet nutrition science are preferable.

Typical Development Workflow

Pet food OEM development generally follows these steps:

• Step 1: Concept design: Define the target (dog/cat, age group, size), product type (complete food/treat), and differentiators (ingredients, functional benefits, brand concept).
• Step 2: Consultation with the OEM manufacturer: Share your concept and confirm ingredient sourcing, manufacturing format, lot quantities, and estimated pricing.
• Step 3: Prototyping and palatability testing: The OEM manufacturer produces prototypes that are tested on actual pets for palatability. Multiple rounds of prototyping are typically needed to finalize the recipe.
• Step 4: Package design and labeling: Create packaging based on your brand's design concept and develop labeling compliant with Japan's Pet Food Safety Act.
• Step 5: Mass production and quality inspection: Begin production and conduct quality inspections (nutritional analysis, microbiological testing, etc.).
• Step 6: Sales launch: Launch on your own e-commerce site, pet shops, and pet product e-commerce platforms.

Sales Channels and Customer Acquisition

Pet food sales channels have become increasingly diverse.

• Your own e-commerce site: Lets you communicate your brand story directly with higher profit margins. Subscription (recurring purchase) models pair especially well with pet food.
• Pet product e-commerce marketplaces: Listing on pet-specialty e-commerce platforms enables efficient reach to pet owners.
• Pet shops and grooming salons: In-store placement builds credibility. Combine with sample distribution for effective product introductions.
• Veterinary clinics: For therapeutic diets and functional food, a veterinary recommendation is a powerful sales driver.
• Social media marketing: Pet photos and videos on Instagram and TikTok generate high engagement and are extremely effective for pet food brand customer acquisition. Building relationships with pet owner communities supports long-term brand growth.
