How to Start a Pet Food Business

Pet food in the United States is regulated at both the federal and state level. Three entities play distinct roles:

FDA (Food and Drug Administration) has primary federal authority over pet food under the Federal Food, Drug, and Cosmetic Act (FFDCA). FDA regulates pet food manufacturing facilities, enforces Current Good Manufacturing Practices (CGMPs), requires facility registration, and can take enforcement action against adulterated or misbranded products. FDA also administers FSMA (the Food Safety Modernization Act), which imposes preventive control requirements on animal food facilities.

State Departments of Agriculture regulate pet food at the state level through commercial feed laws. Almost every state requires pet food manufacturers and distributors to obtain a commercial feed license or registration before selling products in that state. State feed control officials inspect facilities, review labels, and collect tonnage reports. This is usually the first license you need.

AAFCO (Association of American Feed Control Officials) is not a regulatory agency and has no enforcement authority. Instead, AAFCO is a voluntary membership association of state and federal feed regulators that develops model regulations, ingredient definitions, and labeling standards. Most states adopt AAFCO model regulations into their own commercial feed laws, making AAFCO standards effectively mandatory in practice.

No. This is one of the most common misconceptions among aspiring pet food entrepreneurs. Cottage food laws (also called home food processing laws, home bakery laws, or home kitchen laws) apply exclusively to certain human food products made in a home kitchen. Pet food, pet treats, dog biscuits, and animal feed are explicitly outside the scope of cottage food laws in every US state.

The regulatory distinction is fundamental: cottage food laws are administered by state Departments of Health (or equivalent), while pet food falls under state Departments of Agriculture and the FDA. These are entirely separate regulatory frameworks with different agencies, different licenses, different labeling requirements, and different inspection standards.

What this means in practice: you cannot simply obtain a cottage food permit and start selling pet treats. You will need a commercial feed license from your state Department of Agriculture, FDA facility registration, AAFCO-compliant labeling, and potentially a food safety plan under FSMA. The barrier to entry is higher than cottage food, but the market opportunity is also significantly larger.

Some states may allow you to produce pet food in a home kitchen if it meets commercial standards, while others require a dedicated commercial facility. Your state's commercial feed regulations will specify the facility requirements.

The cornerstone of pet food regulatory compliance is your state commercial feed license. This license (variously called a commercial feed registration, feed manufacturing license, or pet food manufacturer permit depending on your state) authorizes you to manufacture and sell pet food within your state.

Typical requirements include:

The process typically takes 2-8 weeks from application to license issuance, though states with label pre-review requirements may take longer. Some states also require a facility inspection before issuing the license.

While AAFCO itself does not enforce regulations, its model rules and ingredient definitions are adopted by most states and form the practical standard for pet food compliance in the United States.

Key AAFCO standards you must follow:

Pet food labels are one of the most heavily regulated aspects of the business. A compliant label must include all of the following elements:

Many states require label pre-approval before you can sell products. This means submitting your labels to the state feed control official for review. Labels that do not meet AAFCO standards will be rejected, delaying your launch.

Common label mistakes that cause rejections: using non-AAFCO ingredient names, incorrect guaranteed analysis formatting, missing calorie content, unsubstantiated health claims, and incorrect use of terms like "natural" or "organic."

The FDA Food Safety Modernization Act (FSMA) applies to pet food facilities under 21 CFR Part 507 (Preventive Controls for Food for Animals). However, small businesses may qualify for significant exemptions.

Qualified Facility Exemption: If your facility's average annual sales are less than $500,000 (adjusted for inflation) AND you sell more to qualified end-users (consumers, restaurants, retailers in the same state or within 275 miles) than to non-qualified end-users, you are a "qualified facility." Qualified facilities are exempt from the requirement to have a written food safety plan with hazard analysis and preventive controls.

What qualified facilities must still do:

Very Small Business: Facilities with average annual sales under $2.5 million had an extended compliance timeline but are now fully subject to Part 507 requirements (unless they also qualify as a qualified facility).

Even with the qualified facility exemption, following good manufacturing practices and having a basic food safety plan is strongly recommended to protect your customers, your pets, and your business.

If you sell pet food online, you almost certainly need to register in multiple states. The key principle: you generally must hold a commercial feed license or registration in every state where your product is received by a customer, not just your home state.

How online sales trigger multi-state registration:

Practical approach for new businesses:

1. Start with your home state license.

2. Expand to 5-10 high-demand states based on your sales data.

3. Prioritize states where you receive the most orders.

4. Budget $2,000-$5,000 annually for multi-state registration fees once you reach 15+ states.

5. Consider limiting your shipping zones initially to states where you are registered.

Some states have reciprocity agreements or streamlined registration for products already approved in another state. A few states do not require separate registration if you are only distributing (not manufacturing) and the product is already registered by the manufacturer.

Multi-state compliance is one of the most complex aspects of running a pet food business. Our platform tracks registration requirements and deadlines across all 50 states.
