Should I change food gradually even if it's the same brand? General Dog Discussions
I give my 7 year old Lab mix Science Diet Adult dog food. She is getting older now and it seems that she is less active, so I bought her Science Diet for dogs 7 years old and older. Should I switch her food gradually by mixing it in with the old, even though it is the same brand?
