Chicken, rice, a few vegetables: more and more owners cook their dog’s meals themselves, convinced it’s healthier than kibble. It’s a loving gesture. But veterinarians are raising a red flag about this increasingly popular practice, and the research backs them up.
The practice: homemade dog food
Cooking for your dog has become a trend, driven by distrust of processed food and by recipes shared online. The intention is good. The problem is what’s missing from the bowl.
A dog doesn’t have the same nutritional needs as a human. It needs precise amounts of calcium and phosphorus, specific vitamins, trace elements and fatty acids. A diet of “chicken and rice” or “chicken and sweet potato,” even varied, rarely covers all of them.
What the research found
A study from the UC Davis School of Veterinary Medicine, published in the Journal of the American Veterinary Medical Association, analyzed 200 homemade dog food recipes from 34 sources, including books, websites and even veterinary textbooks. The result:
- 95% of the recipes were deficient in at least one essential nutrient.
- More than 83% had several deficiencies.
- The most common gaps involved choline, vitamin D, zinc and vitamin E.
- Only the 4 recipes written by board-certified veterinary nutritionists met adult-dog standards.
The researchers add that rotating recipes “for variety” doesn’t fix the problem, because many recipes share the same gaps.
The risks for the dog
Deficiencies don’t show up overnight. Over months, an unbalanced diet can lead to bone and joint problems, skin and coat issues, weakened immunity, or, according to veterinarians, urinary stones in some dogs. Puppies, whose skeleton is growing, are the most exposed. And some “healthy” human foods are toxic to dogs: grapes and raisins, onions, garlic, chocolate, xylitol.
If you still want to cook for your dog
- Ask your vet before changing your dog’s diet.
- Use a recipe formulated by a board-certified veterinary nutritionist, tailored to your dog’s age, size and health.
- Follow it exactly, including the supplements: they are not optional.
- Or go halfway: a complete commercial food as a base, with small portions of plain cooked food as a topper.
The limit
Homemade food is not dangerous in itself: a well-formulated homemade diet can be excellent. The danger is the improvised recipe. And every dog is different, which is exactly why the advice of a vet matters.
Choosing the right dog for your family matters as much as feeding it well, as we explained with the breeds an expert wouldn’t pick for young kids. And to understand your dog better, see why a dog that goes wild when you come home isn’t always happy.
A real recipe, a vet’s opinion and no improvising. That’s the trick.
