Personally I wouldn't try this. Dog food can actually get kinda complicated because even though it dry the ingredients in it still have a percentage of water in them. You have to crunch some figures to know exactly what you are feeding your dog in terms of crude protein, fat, fiber and carbs.
"Prescription" food (the kind you can only get at the vet) are the best and even then there are SO many different kinds for different needs. Adults don't eat the same as puppies, certain breeds don't eat certain ones (Dalmatians should be on vegetarian for example) and all kinds of things.
In other words if it's that complicated for dogs with
dog food, you can imagine how it would be to feed another species this diet!
Just a few thoughts.
