Pet Supplement Manufacturers

28 pet supplement manufacturers have a GMP-certified facility (NSF/ANSI 455-2) or an Informed Manufacturer certified facility, 27 of them in the United States (top states: Florida 7, New York 4, Arizona 2); for 10 of them a USDA Organic certificate lists pet supplement items, and 21 say on their own website that they make pet supplements. USDA Organic item lists checked October 1, 2026; website claims checked October 16, 2026; certification data checked November 1, 2026.

Looking for a pet supplement manufacturer in the USA? Compare the listings below for dog supplement manufacturing and private label pet supplements. Use the country and state links to narrow your shortlist.

Every company on this page has at least one manufacturing or packaging facility on a public registry we check (NSF/ANSI 455-2 or Informed Manufacturer), and either its USDA Organic certificate lists pet supplement items or its own website says it makes pet supplements; each listing says which. The certification and the USDA Organic item list come from public registries and were found there on the date shown. The item list covers organic products only, and it is the certifier’s record of what the operation handles, not a test of any product. A pet supplements claim on a company’s website is the company’s own: we record it with a quote and the date we checked, and we have not verified it.

Rules for animal supplements differ from those for human dietary supplements, and from country to country. Ask each manufacturer which facility makes its pet products and whether it is the certified one.

Questions buyers ask

How do I choose a pet supplement manufacturer in the USA?

Start with the USA list, check the exact facility and its certificate scope, and confirm dog supplement manufacturing and private label pet supplements. Ask for the minimum order, first-run and reorder lead times, testing plan and an itemized quote. Website capabilities are company claims unless a separate registry basis is shown; confirm the proposed work directly.

What should I ask a pet supplement manufacturer?

Ask which facility makes the pet products and whether it is the certified one, which formats they make (chews, powders, liquids or tablets), which animals they formulate for, and how they support the label claims you plan to make. Check the rules for animal products in each market you sell in.

Do you verify that these companies make pet supplements?

No. A company is listed here when one of its facilities is on a public registry we check and either its USDA Organic certificate lists pet supplement items or its own website says it makes pet supplements. The USDA Organic item list is the certifier’s record of what the operation is certified to handle organically, as we found it in the USDA Organic Integrity Database on the date shown; it covers organic items only and is not a test of any product. A website claim is the company’s own statement: we keep the quote, the page and the date we checked. Each card says which applies. Confirm either with the manufacturer before you rely on it.

What should I ask for in a quote request?

Ask for minimum order quantity, lead times, formulation options, testing and certificates of analysis, in writing. In detail: ask about minimum order quantity (MOQ) per SKU, lead time for a first run and for reorders, whether they offer stock formulas or custom formulation, who sources raw materials, what testing they run (identity, potency, microbiological, heavy metals) and whether you receive a certificate of analysis (COA) per batch, and whether they support the label claims you plan to make. Terms vary widely by manufacturer, so compare written answers rather than assumptions.

How do I verify a manufacturer’s GMP certification myself?

Ask the manufacturer for their current certificate and the exact facility address it covers, then look that facility up on the certifier’s public listing (for NSF/ANSI 455, NSF’s online listings). Certificates apply to specific sites, so make sure the facility that will make your product is the one listed. Each profile here links to the public listing we checked and the date we checked it.
