How to Start a Pet Food Business
A starting point for researching facility registration, state feed rules, labeling, and destination-state requirements.
Who Regulates Pet Food?
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) oversees animal-food safety and labeling at the federal level. Facility registration, manufacturing practices, and preventive controls depend on the operation and applicable exemptions. Start with FDA's animal-food business guidance rather than assuming every home business has the same duties.
State feed control officials administer their jurisdiction's feed and pet-food rules. Ask each relevant agency about licensing, product registration, label review, inspections, and reporting before selling there.
AAFCO (Association of American Feed Control Officials) develops model regulations, ingredient definitions, and labeling guidance. AAFCO does not approve products or enforce laws; the rules adopted by your jurisdiction determine your obligations.
Is Pet Food Covered by Cottage Food Laws?
Do not assume a human cottage-food permission authorizes pet treats. Animal food has its own federal and state requirements; ask the state's feed control official which rules apply to the proposed product and home-production setup.
Human-food and animal-food permissions address different products. Agency responsibilities also vary by jurisdiction; use the feed control official's guidance for the pet-food operation rather than relying on a human cottage-food checklist.
Check state feed licensing, ingredient suitability, labeling, and facility requirements before selling. FDA's business guidance distinguishes in-home operations from facilities that must register; registration and preventive-control duties depend on the operation and applicable exemptions.
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.
State Licensing Requirements
State requirements may concern the business, individual products, or both. Confirm what approval covers your operation and whether separate requirements apply to each destination state.
Ask the agency whether it needs:
Completed application form from your state Department of Agriculture
Current application, product-listing, or tonnage fees set by the relevant state
Facility information (address, description of manufacturing area, equipment list)
Product labels and any required pre-approval for the proposed sales
Evidence supporting nutrient guarantees, including any required testing
Production or distribution reports and the applicable reporting period
Renewal dates and any business, product, or tonnage fees
Ask the agency about current processing times and inspections before setting a launch date. Requirements and lead times vary by operation and state.
Use the platform's recorded state references to prepare questions, then confirm current requirements, fees, and forms with the agency.
AAFCO Compliance
Read AAFCO's model guidance alongside your jurisdiction's adopted rules. Model guidance is not individual product approval.
Label and formulation questions to review:
Ingredient definitions: Use the correct AAFCO-defined ingredient name where one exists; otherwise use its common or usual name. Confirm that the ingredient itself is suitable and permitted for its intended animal-food use.
Guaranteed analysis: AAFCO's pet-food guidance describes protein and fat minimums followed by fiber and moisture maximums. Establish product-specific guarantees with adequate evidence; additional guarantees and any product exceptions need regulator review.
Nutritional adequacy statement: A complete-and-balanced claim needs substantiation. Products conspicuously identified as snacks, treats, or supplements have a nutritional-adequacy statement exemption under the model rules. Other products may need an intermittent-or-supplemental purpose statement; confirm which category applies.
Naming conventions: AAFCO has strict rules about product names based on ingredient content (the 95%, 25%, 3%, and flavor rules).
Calorie content: Check the applicable calorie statement and units under the adopted rules for your product category and claims.
Labeling Requirements
Review the elements below for applicability to your product. A complete-and-balanced food and a conspicuously labeled treat do not have identical statement requirements:
Product name (following AAFCO naming rules)
Species designation ("for dogs," "for cats," etc.)
Guaranteed analysis (protein, fat, fiber, moisture at minimum)
Ingredient statement (defined name where one exists, otherwise common or usual name; descending weight order)
Nutritional adequacy statement (where applicable; check the model-rule exemption for conspicuously labeled snacks, treats, or supplements)
Feeding directions (required for complete-and-balanced foods; optional under the model rules for snacks or treats without that claim)
Net weight / net quantity
Manufacturer or distributor name and address
Calorie content statement (check the applicable product and claim rules)
Ask the destination state's official whether label submission or pre-approval is required. A model-rule checklist does not establish that your label is approved.
Review ingredient identities, guarantee formatting, applicable calorie statements, and the evidence for descriptive or health claims. Terms such as "natural" or "organic" need their own applicability check.
FSMA for Small Businesses
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 facilities: FDA describes two eligibility paths: a very-small-business test based on animal-food sales plus the value of food handled without sale, or a separate sales-and-qualified-end-user test. Both use multi-year averages and inflation-adjusted limits. Check FDA's current definitions and cutoffs rather than using a fixed dollar figure from a guide.
What qualified facilities must still do:
Follow Current Good Manufacturing Practices (CGMPs)
Submit Form FDA 3942b when required, including the biennial renewal period; re-evaluate qualification annually and report status changes under FDA's instructions
Attest to FDA that the facility qualifies, plus either hazard identification and preventive-control monitoring or compliance with applicable non-Federal food safety law. The supporting attestations are alternatives submitted to FDA, not two customer-facing label statements
If using the non-Federal-law attestation instead of the hazard-and-controls attestation, provide the facility's name and complete business address to consumers as specified in 21 CFR 507.7(e). The required location depends on whether a packaging label is required
Maintain food facility registration if the business is required to register; private residences and other exempt operations need a separate applicability check
Very small businesses: This is one of the qualified-facility paths, not merely an expired compliance extension. Qualified status changes some preventive-control requirements; it does not remove applicable manufacturing-practice, labeling, state, or other duties.
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.
Online Sales & Multi-State Registration
Online selling does not remove destination-state requirements. Check whether each state where the product will be distributed requires a business license, product registration, label review, or another approval.
How online sales trigger multi-state registration:
For an order shipped from Texas to Ohio, check Ohio's current distribution and registration rules before accepting the sale.
You list products on Etsy or Amazon. Every state a customer ships to may require registration.
Even small-volume sales into a state can trigger the requirement.
Practical approach for new businesses:
1. Start with your home state license.
2. Research a manageable set of destination states based on your selling plans.
3. Prioritize states where you receive the most orders.
4. Build a fee and renewal budget from each destination state's current agency records; there is no universal multi-state price.
5. Consider limiting your shipping zones initially to states where you are registered.
Ask each destination agency about exemptions, distributor obligations, and whether another business's existing product registration covers your proposed activity. Do not assume reciprocity.
Review the platform's recorded sources and verification dates for each destination. Missing records are not permission to sell; confirm requirements with that state's feed control official.
