I think a vet would be better able to answer this question by looking at the ingredients and nutritional information on the bag. I am a customer who feeds it to my adult dog. 

Hi Texas Shep, Good day! No, none of our WholeHearted food contains animal by-products unless the part of the animal is specifically called out (i.e. Chicken Liver). The difference between chicken, chicken meal and chicken by-product as defined by AAFCO is: Chicken: the clean combination of flesh and skin with or without accompanying bone, derived from the parts or whole carcasses of chicken or a combination thereof, exclusive of feathers, heads, feet and entrails. (Translation: Chicken meat, skin and bone) Chicken Meal: Chicken (see above) which has been ground or otherwise reduced in particle size. (Translation: Chicken meat skin and bone that is ground into small pieces. Chicken meal is a dry, solid material that can be made into kibble.) Chicken by-product: the clean parts of the carcass of slaughtered chicken, such as necks, feet, undeveloped eggs and intestines, exclusive of feathers, except in such amounts as might occur unavoidable in good processing practice. (Translation: Chicken necks, unborn eggs, feet and organs) Thanks,

Hi RobinPetMom, Good day! It is 1.0% As Fed. Thanks,

Hi North House Paul, This product is manufactured in the US with globally source ingredients. Thanks,

Hi Donnayanswer, We suggest that you consult your vet before giving any new food or food combination to your pet Thanks,

Definitely, i give it to my toy poodle mix who's 15 and has only a few teeth so it needs to be soak and get soft for him but my 60 lb lab mix also loves it so it works for both!

Depends what the allergies are from. Some dogs are allergic to grains so yes would be good. But if has allergies to chicken, then no.

I did not see anything on the labeling stating that the chickens were raised on a free range, cruelty free farm with their feet protected from falling through the cage-something tells me if they were, we'd sure know about it, if you find one please let me know. Maybe Petco knows.
