Hi. I'm new to the forum (this is my first post) and have my first pitbull puppy. I purchased him from a city about 3 hours from home a week ago today, where he was being fed Diamond dogfood - they sent me home with a little, but we don't have it here so my pit - Kunda, was switched to Wellness Super5Mix for large brred puppies, and he's developed terrible diarrhea after a couple of days on the new diet. Should I hold off feeding him and let his stomach settle, or just push thought with faith that he'll adjust to the new food? He's lost a little weight but seems fine in all other aspects. I'll schedule him for first vet appointment with me soon, but thought I could get a jump-start on helping him here.
