Private label dog shampoo is pet shampoo made by a contract manufacturer and sold under your brand. It sits in an unusual regulatory spot. The FDA treats a plain cleansing shampoo for pets as a “grooming aid”, not a cosmetic, and doesn’t regulate it. But add a claim like “treats hot spots” or list an “active ingredient” and it can become an unapproved animal drug. Add a flea or tick claim and it’s a pesticide under EPA rules, which needs an EPA registration number, and Amazon approval to sell. Minimums range from no minimum at one Canadian maker to 1,000 units per SKU at an overseas factory, and most US makers quote on request.
Below I compare manufacturers and explain the three regulatory lanes, so you can decide which kind of dog shampoo to launch.
Private label dog shampoo manufacturers
From each company’s own site, checked October 11, 2026:
| Manufacturer | Location | Published minimum | Lead time | Notes |
|---|---|---|---|---|
| Natural Pet Innovations | Earth City, Missouri | “Low minimums” (no number) | Says “30 Day Concept to Completion” | Natural dog shampoo range; US-made |
| Cassco Bio Labs | Bridgeton, Missouri | Says lowest MOQs in the industry (no number) | “Quick lead times” (no number) | States all products made in the USA |
| Tropical Products | Salem, Massachusetts | Ask | Ask | 50,000 sq ft facility |
| Glo-Marr Products | Lawrenceburg, Kentucky | Ask | Ask | Pet shampoos, conditioners and grooming products; custom formulations |
| Elixderm | Mississauga, Canada | States no MOQ | Plans of 1-3 weeks | Manufacturing location not stated |
| Metro Private Label | Produces in China | 1,000 units per SKU; pilot runs from 500 | Samples 3-4 weeks; production 4-6 weeks | Its page shows other figures in a table, so confirm in writing |
US pet shampoo makers rarely publish numbers. In practice, you’ll send an enquiry with your formula idea, bottle size and expected volume, and get a quote back. Ask each maker to confirm its minimum per scent and per bottle size, because those are counted separately more often than not.
My take: start with a US maker’s stock formula, such as an oatmeal or unscented shampoo, under your own label. Custom formulas, fragrances and claims add cost and risk, so save them for your second product.
Lane 1: grooming shampoo (not regulated by FDA)
The FDA’s compliance policy guide on animal grooming aids explains the key point. Under federal law, the term “cosmetic” is limited to products for humans. Products intended only to cleanse or beautify animals are grooming aids, and the FDA says they aren’t subject to the Food, Drug, and Cosmetic Act or regulated by the agency. An FDA consumer page puts it simply: the FDA regulates medicated shampoos but not “cosmetic” shampoos for animals.
Because pet grooming aids aren’t cosmetics under that law, the human cosmetic rules, including MoCRA facility registration and product listing, don’t map onto them in the same way. That doesn’t mean anything goes. You still need honest labels, accurate ingredient information and safe products, and your wording decides which lane you’re in.
Typical grooming claims that stay in this lane:
- Cleans and deodorizes
- Leaves coat soft and shiny
- Gentle, tear-free formula (if true)
- Fresh scent
Lane 2: medicated shampoo (an animal drug)
The same FDA policy guide says a product sold as a grooming aid becomes a drug if it’s intended to cure, treat, mitigate or prevent disease in animals, or to affect the structure or function of the body. The FDA looks at the claims, formulation, labeling and promotional materials, and says a product represented as a drug, for example by listing an “active ingredient”, may be considered a drug. An animal drug that isn’t approved, conditionally approved or index listed is treated as unsafe and adulterated.
Claims that can push a dog shampoo into drug territory include “treats hot spots”, “antifungal”, “relieves allergies”, “medicated” or “stops itching due to skin infections”. Honestly, I’d keep all disease and skin-condition language off a private label shampoo unless you’re working with a manufacturer that already holds the right approvals and knows the animal drug process.
Lane 3: flea and tick shampoo (an EPA pesticide)
Flea and tick shampoos are pesticides. The EPA lists shampoos among the forms that flea and tick products come in, alongside collars, sprays and spot-ons. Historically, the EPA and FDA split oversight by whether a product is absorbed into the bloodstream (FDA) or stays on the skin (EPA). In February 2023 the agencies proposed moving certain flea and tick pet products from EPA to FDA; the EPA describes this as a proposal.
For an EPA-registered pesticide, the label must show the registration number, preceded by “EPA Reg. No.”, and the producing establishment number, preceded by “EPA Est.”. The EPA also warns consumers that a missing registration number is a sign of a counterfeit pet pesticide.
The “natural” exemption, and its limits. Some flea shampoos qualify as minimum risk pesticides under FIFRA section 25(b), which exempts them from federal registration. The EPA lists six conditions, including:
| Condition | What it means |
|---|---|
| Approved active ingredients only | From the EPA’s minimum risk list |
| Approved inert ingredients only | From EPA’s list or certain food items |
| Full ingredient disclosure | Actives shown as a percentage by weight |
| No public health claims | “Controls ticks” is fine; “controls ticks that carry Lyme disease” isn’t |
| Company details on label | Name, street address and phone |
| No false or misleading statements | Applies to all label claims |
The EPA notes that most states still require minimum risk products to be registered at state level. So “exempt” federally doesn’t mean “no paperwork”.
Selling dog shampoo on Amazon
A plain grooming shampoo lists like other pet supplies. Flea and tick shampoos are different. Amazon’s US pesticide policy says:
- All pesticides must carry a valid EPA registration number and establishment number, or qualify for an exemption.
- Approval from Amazon is required to sell them. Sellers must be US residents and complete Amazon’s training with a score of 80% or higher.
- Every listing needs a pesticide marking attribute with the EPA details or the exemption.
- Claims like “safe”, “non-toxic” and “all natural” are prohibited, as are public health claims.
- Amazon notes that products with ingredients such as pyrethrin or permethrin don’t necessarily qualify as minimum risk.
The policy applies to any product that claims to prevent, destroy, repel or mitigate a pest, wherever the claim appears in the listing, including images. A “repels fleas” line in one photo is enough to pull a grooming shampoo into the pesticide rules.
Questions I’d ask a pet shampoo maker
Quotes from pet shampoo makers can look alike. The answers to a few plain questions tell them apart.
Is the minimum per scent, per size or per order? A “low minimum” that applies to each scent and each bottle size can still add up to thousands of bottles.
Do you have stock formulas? A tested base formula is cheaper and faster than a custom one, and the maker already knows how it behaves in storage.
What pH and preservative system do you use? Dog skin isn’t human skin. My view is that a maker who can explain its formula choices clearly is a maker who tested them.
Can you handle EPA products? If you might add a flea shampoo later, ask whether the plant makes registered pesticides or only grooming products. Many don’t, and switching makers mid-range is painful.
What’s the shelf life, and how is it dated? Groomers and retailers will ask. So will Amazon reviewers, eventually.
Short, specific answers are a good sign. Vague ones usually mean the real work happens somewhere else. In practice, I’d also ask for two or three references from current private label clients, ideally brands of a similar size to yours.
How I’d launch a dog shampoo brand
- Choose your lane first: grooming only, medicated or flea and tick. For a first product, I’d pick grooming only.
- Start with a stock formula from a US maker and request samples.
- Write your label claims before ordering, and check none of them implies treatment or pest control.
- Test on real dogs with the maker’s guidance, watching for irritation and how well it rinses.
- Choose packaging: a 16 oz bottle for retail, a gallon for groomers.
- Add a conditioner or spray once the shampoo sells.
My view: the grooming lane is crowded, so the brand needs a clear angle, such as sensitive skin wording that stays within grooming claims, a groomer-size product, or a scent people remember. Reviews in this category often mention smell and lather, so test both with real owners before launch.
Mistakes new dog shampoo brands make
- Disease claims on a grooming product, like “cures itchy skin”.
- Flea claims without EPA registration or a valid exemption.
- “Non-toxic” and “safe” wording on pesticide listings, which Amazon prohibits.
- Assuming a 25(b) product needs no state registration.
- Skipping wash and rinse tests before ordering thousands of bottles.

FAQ
What is the minimum order for private label dog shampoo?
It varies. One Canadian maker states no minimum, an overseas factory lists 1,000 units per SKU with 500-unit pilot runs, and most US makers quote on request.
Does the FDA regulate dog shampoo?
Not plain grooming shampoo. The FDA calls it a grooming aid and doesn’t regulate it. Medicated shampoos with treatment claims are regulated as animal drugs.
Is flea and tick shampoo regulated differently?
Yes. Flea and tick shampoos are pesticides. Most need an EPA registration number and establishment number on the label, unless they meet all six minimum risk conditions.
Can I sell flea shampoo on Amazon?
Only with Amazon’s approval. Sellers must be US residents, pass Amazon’s training, and provide EPA registration details or an exemption for each product.
Can I call my dog shampoo “natural” or “non-toxic”?
Be careful. On pesticide products, Amazon prohibits “safe”, “non-toxic” and “all natural” claims. On grooming shampoos, any claim must be truthful.
What claims turn a dog shampoo into a drug?
Claims to treat, cure, mitigate or prevent disease, or to affect the body’s structure or function, such as “treats hot spots” or “antifungal”.
