5 Quality Markers Every Pet Parent Should Check Before Buying CBD Products

The pet CBD market is growing fast. So is the number of products that do not deliver what their labels promise. Here is how to tell the difference before your dog or cat tries a single drop.

You have done your research. You have read about how CBD may help your dog with stiff joints or your cat with situational anxiety. You are ready to try it. But when you search for pet CBD products, you find hundreds of options at wildly different price points — and they all claim to be “the best.”

Here is the reality: a study evaluating 29 CBD pet products found that only 10 had cannabinoid concentrations within 10% of what their labels claimed. Two contained zero cannabinoids at all. Four were contaminated with heavy metals. Your pet cannot read a label, and they certainly cannot file a complaint. That job falls to you.

These five quality markers will help you separate products worth trying from products worth avoiding. None of them require a chemistry degree — just a few minutes of checking before you click “add to cart.”

1. A Current, Batch-Matched Certificate of Analysis

A Certificate of Analysis (COA) is a lab report from an independent testing facility that verifies what is actually in the product. This is the single most important quality marker for any CBD product, and it is non-negotiable for something you plan to give your pet.

Here is what to check on a COA:

Is it from a third-party lab? The lab should be independent from the company selling the product. Look for ISO/IEC 17025 accreditation, which means the lab meets international standards for testing competence. If the company only offers “in-house testing,” treat that as a red flag.

Does the batch number match? Every COA should reference a specific batch or lot number. That number needs to match the one printed on your product’s packaging. A COA from a different batch tells you nothing about what is in the bottle you are holding.

Is it recent? COAs should be from the current production batch, not from a test run years ago. If the most recent COA on a company’s website is more than a year old, the product may have changed since it was last tested.

What does it test for? A thorough COA covers cannabinoid potency (confirming CBD content and THC levels), pesticides, heavy metals (lead, arsenic, cadmium, mercury), residual solvents, and microbial contaminants. If any of these panels are missing, the testing is incomplete.

Most reputable brands publish their COAs directly on their website, often with a QR code on the product packaging that links to the specific batch report. If you cannot find a COA, or if the company makes you email them to request one, consider that a warning sign.

2. NASC Quality Seal or Equivalent Certification

The National Animal Supplement Council (NASC) operates a quality seal program specifically for animal health products, including pet CBD. Companies that carry the NASC Quality Seal have submitted to biannual independent audits, maintain adverse event reporting systems, and undergo random product testing.

This seal is not a rubber stamp. The NASC audit process checks manufacturing practices, labeling accuracy, and quality control systems. It does not guarantee that a product will work for your pet, but it does confirm that the company follows established standards for making it safely and honestly.

The U.S. Hemp Authority certification is another trust marker, though it applies to hemp products broadly rather than pet products specifically. Companies with this certification have passed audits covering their supply chain, manufacturing, and labeling practices.

Not every good product carries these seals — the certification process costs money and some smaller brands have not pursued it. But when you are comparing two similar products, a NASC seal tips the scale toward the certified one.

3. Clear, Species-Specific Labeling

A quality pet CBD product should make it easy to figure out three things: how much CBD is in each dose, what else is in the product, and how to use it for your specific pet.

CBD per serving, not just per bottle. A label that says “500mg CBD” without telling you the concentration per dropper or per treat is not helpful. You need to know that each full dropper delivers, say, 16.7mg of CBD so you can calculate the right dose for your dog’s weight.

Species-specific dosing guidance. Dogs and cats metabolize CBD differently. A product labeled “for pets” without distinguishing between species is cutting corners. Look for weight-based dosing charts that separate dogs and cats, or products formulated specifically for one species.

Complete ingredient list. You should be able to read every ingredient on the label. Watch for added flavors or carrier oils that might not agree with your pet. Coconut MCT oil is the most common carrier for pet CBD oils and is generally well-tolerated. Avoid products with artificial sweeteners (especially xylitol, which is toxic to dogs), artificial colors, or unnecessary fillers.

THC content disclosure. Full-spectrum products contain trace THC (under 0.3%), which is legal and generally safe for dogs in small amounts. Cats may be more sensitive to THC. The label should clearly state whether the product is full-spectrum, broad-spectrum, or isolate, and the COA should confirm THC levels.

4. Transparent Hemp Sourcing

Where the hemp was grown and how it was processed affects the final product more than most pet parents realize.

U.S.-grown hemp is subject to USDA oversight and state agricultural programs that set standards for cultivation. Hemp grown in other countries may be perfectly fine, but verifying growing practices becomes much harder. Look for companies that name the state where their hemp is grown, not just “USA.”

USDA organic certification on the hemp means the plants were grown without synthetic pesticides, herbicides, or chemical fertilizers. Since hemp is a bioaccumulator — it absorbs substances from the soil — organic growing practices reduce the risk of contaminants ending up in the final product and ultimately in your pet.

Extraction method matters. CO2 extraction is considered the gold standard because it pulls cannabinoids from the plant without leaving behind potentially harmful solvents. Ethanol extraction is also common and generally safe. If a company does not disclose its extraction method, ask — and be cautious if they will not answer.

5. A Company That Answers Questions

This might sound soft compared to lab reports and certifications, but a company’s responsiveness tells you a lot about how seriously they take their products and your pet’s safety.

Before you buy, try contacting the company with a question — about dosing for your pet’s weight, about the source of their hemp, or about a specific ingredient. Companies that care about pet safety respond quickly and with real information, not canned marketing copy.

Also look for whether the company maintains an adverse event reporting system. The NASC requires this for its quality seal members, but any responsible company should have a process for hearing from customers whose pets had unexpected reactions.

Social proof matters too, but read pet parent reviews with a critical eye. Look for reviews that mention specific details — the pet’s size, the dose used, the specific behavior or condition they were addressing — rather than generic praise. Detailed reviews from pet parents whose situations resemble yours are more useful than a thousand five-star ratings with no context.

When to Talk to Your Vet

Before starting any CBD product, talk to your veterinarian. As of 2026, veterinarians in a growing number of states — including California, Colorado, and Maryland — can now discuss CBD more openly with pet parents without risking their licenses. Your vet can help you evaluate products, establish an appropriate starting dose based on your pet’s weight and health history, and monitor for potential interactions with any medications your pet currently takes.

If your vet is not familiar with CBD, the research updates on CBDProducts.com and the veterinary CBD studies tracked by SafeCBD can help you have a more informed conversation together.

The Bottom Line

Choosing a CBD product for your dog or cat does not have to feel like guesswork. Check the COA, look for certifications, read the label carefully, verify the hemp source, and make sure the company behind the product is transparent and responsive.

Your pet trusts you to make good choices for them. These five markers will help you do exactly that.
