Pet's info: Dog | Mixed Breed | Male | neutered

I have 2 dogs and they have been acting uninterested in the new bag of food I got them. Same brand just new bag. They haven't really eaten much of it and now we are noticing black stools from our smaller dog. Not sure about the large dog as we haven't looked at her stools yet.

Black stools could be a sign of bleeding from the upper gastrointestinal tract, as both of them are suffering from lack of appetite, it could either be related to the food or it might be a contagious infection. i would recommend taking them to the vet in order to get it checked as soon as possible, a stool sample might be required.
