What should I check before buying vet recommended dog food?
Start with the AAFCO statement. A feeding-trial statement means the food was tested on dogs, not just formulated on paper. All four picks carry one.
Then look at who makes it. Purina, Hill's and Royal Canin all employ board-certified veterinary nutritionists and own their plants.
Price per calorie is the number most shoppers miss. Here it runs from $1.20 to $1.68 per 1,000 kcal. A $72 bag and an $85 bag are not the same cost to feed.
Finally, match protein to the dog. Science Diet's 20% protein is fine for a couch dog, thin for a working one. If your dog has a history of loose stools, a single animal protein source makes an elimination trial easier to run.
