"WSAVA approved" isn't an official certification. The World Small Animal Veterinary Association (WSAVA) publishes Global Nutrition Guidelines with questions owners can ask a pet food company about nutrition expertise, quality control and testing. Brands that answer them clearly are easier to trust, but the WSAVA doesn't approve, rank or endorse any specific food.
You'll see "WSAVA compliant," "meets WSAVA guidelines" or "WSAVA approved" on some websites and in some marketing. Because the WSAVA doesn't certify foods, treat the phrase as a company's own claim and check it yourself. This guide explains what the WSAVA actually published, why the guidelines matter, what "compliant" doesn't tell you, how to check a brand step by step, and a simple scorecard you can use. Once you pick a food, set the portion with the dog food calculator.
What the WSAVA actually published
The WSAVA Global Nutrition Committee created a checklist to help vets and owners evaluate pet food manufacturers. Its core questions are:
- Is there a qualified nutritionist (a board-certified veterinary nutritionist or a PhD in animal nutrition) employed by the company?
- Who formulates the diets, and what are their credentials?
- Which nutritional adequacy standard is used (AAFCO or FEDIAF), and were the diets tested by feeding trials or only formulated?
- Where are the foods produced and manufactured?
- What quality control measures are used to ensure consistency and safety of ingredients and finished products?
- Can the company provide a complete nutrient analysis for the product, not only the guaranteed analysis?
- What is the energy (calorie) content of the food per gram, can or cup?
Some lists condense these into five headline questions, but the idea is the same: find out whether real nutrition expertise and real quality control stand behind the food.
Why the guidelines matter
Two dog foods can have similar labels but differ a lot in how carefully they're formulated and tested. A company with an in-house nutritionist, feeding trials and its own plants has more ways to catch problems, including nutrient imbalances and contamination. History shows why it matters: several recalls and diet-related diseases have been traced to formulation or manufacturing errors that stronger oversight might have caught earlier.
What "WSAVA compliant" does not tell you
- It doesn't guarantee the food is right for your dog's age, size or health.
- It isn't a legal term or a regulatory seal.
- It doesn't judge ingredients, price or palatability.
- It doesn't replace veterinary advice for dogs with medical conditions.
- It doesn't mean the food is better than one that hasn't addressed the questions publicly.
- It doesn't cover individual recipes: a company may be strong overall but have a weaker product.
How to check a brand yourself
- Visit the company's website and look for a named nutritionist and their credentials.
- Look for the AAFCO statement on the product and whether it lists feeding trials.
- Email or call customer service and ask the WSAVA questions. Good companies answer directly and quickly.
- Request the full nutrient profile and kcal per cup.
- Check recall history on the FDA website, and see how the company responded.
- Ask your vet whether they've seen patients do well on it.
- Keep a record of answers so you can compare brands.
Vague answers, "proprietary" replies or no response are warning signs.
Worked example: a scorecard
Give a brand one point for each yes:
| Question | Brand A | Brand B |
|---|---|---|
| Qualified nutritionist on staff | Yes | No |
| AAFCO feeding trials | Yes | Formulated only |
| Owns its plants | Yes | No |
| Shares full nutrient analysis | Yes | No |
| Lists kcal per cup | Yes | Yes |
| Score (out of 5) | 5 | 1 |
Brand A isn't automatically right for your dog, but it gives you much better information to work with. Brand B isn't necessarily unsafe, but you'd be trusting it with less evidence.
Applying it to cat food
The same questions apply to cat food, because the nutrition science and manufacturing issues are similar. Use them for any pet food.
Next steps once you've chosen
- Check the AAFCO life-stage statement matches your dog.
- Portion by calories, using the dog calorie calculator.
- Switch gradually over 7-10 days.
- Reassess body condition every month or two.
When to call your vet
Talk to your vet before switching if your dog has allergies, kidney, liver, heart or digestive disease, or is a growing large-breed puppy. Call promptly for vomiting, diarrhea, itching or weight changes after a diet change.
