Homemade Dog Food: The Benefits, the Risks, and What Most Guides Get Wrong
Published September 15, 2024
The appeal of homemade dog food is obvious: you know exactly what's in it, you can tailor it to your dog's needs, and there's something satisfying about cooking for your pet. But a consistent finding across studies of home-prepared canine diets is that the majority are nutritionally incomplete.
What the Research Shows
A 2013 study published in the Journal of Nutritional Science evaluated 200 home-prepared dog food recipes from books and websites. Over 95% of them were deficient in at least one essential nutrient. The most commonly deficient nutrients were zinc, copper, vitamin D, and essential fatty acids.
The Most Common Mistakes
- No calcium supplementation (plain meat is extremely calcium-deficient)
- Forgetting organ meat (the primary dietary source of many fat-soluble vitamins)
- Using lean muscle meat only (insufficient fat for energy and fat-soluble vitamin absorption)
- Vitamin D deficiency (dogs cannot synthesise enough from sunlight alone)
How to Do It Properly
If you're committed to home preparation, use a recipe formulated by a board-certified veterinary nutritionist, and supplement rigorously. The WSAVA (World Small Animal Veterinary Association) guidelines provide a framework for evaluating any home diet recipe.
