When you switch a dog from one kibble to another you really aren't just changing ONE ingredient (the chicken in your case). You need to compare ALL the ingredients in two foods and see what's different.

Having an allergy to a protein is rare in dogs. Yes, it does happen but you can't make that judgement using kibble.

 

Look for a fish based, grain free, limited ingredient food.

I see more people post that their dogs stop eating TOTW after a bit and have to add toppings. Mine did too. My feeling is if you have to bribe your dog with toppings to get them to eat the food, maybe the problem is actually the food.

 

Thanks for the reply. I was feeding her Blue Buffalo Chicken & Brown Rice Lg breed puppy. So it could be any one of several ingredients. Not sure but it sounds like I need to make a list of what is different, take it to the vet & have allergy tests done.

 

I was feeding my pup Canidae chicken and rice and was dealing with itchy skin, and runny poop after a few vet visits and coming back neg on all tests giving meds just in case I changed his food to Canidae bison and lamb and the itchy skin and runny poop is gone. I can't feed him any chicken based products .
