I just kind of eye-ball it for canned, to be honest. I use just enough canned to coat the kibbles evenly (a few spoonfuls of canned over 1/3-1/4 cup dry for my dachshund, and a whole 13 oz can to 3-4 cups split between my big guys) and if I notice undesirable weight change, I adjust accordingly.
For “fresh” toppers, as long as it’s not making up more than about 20% of the dogs diet, it’s fine. That 20% can mean daily toppers, or even a whole meal once a week or so of a raw meaty bone or something. No need to make it all scientific, really. Have fun with it!
As for size and breed specific marketing, it’s pretty useless. Keep life interesting and switch it up. I’m actually feeding all my dogs on Wellness Toy Breed Complete Health right now– even the 130 pounder! I shoot for 25% and up (the higher the better, but I use coupons for my dog food, so I can’t be too picky), and as high callorie as possible. This one happened to fit the bill with 30% protein and 502 calories per cup, and be free, plus money back, after coupons.
Nothing wrong with questions! If you don’t ask, you don’t learn. 🙂
