I follow a lot of bully breed Facebook pages & had a conversation about kibble. I had my dogs on Infinia Bison & Potato, which was ok, but Boomer was still itchy around his butt &, well, his penis (penile discharge irritating his belly & thighs). I had a feeling it was the potato. Someone recommended Hill’s Prescription Diet Z/D; she said her white APBT had no allergic reactions on it. Z/D is sold by any local veterinarian, so it was easy to get, & in fact I had to stop by my vet to get Madeline’s eye ointment, so I picked up a bag just to try it out. It was just over $100 for a 24 lb bag, if I recall correctly. I no longer have the bag since I took it back to the vet for a refund.
I began introducing the Z/D gradually. It took a few days to reach a 50-50 Hill’s-Infinia mix. And all of a sudden Boomer’s moderate itching turned into full blown, entire torso friable pus & utter misery. He wouldn’t let me sleep; he kept crying. I thought he needed to go outside to pee, but when I got a look at him it was pretty dreadful. Image in next paragraph; it’s not NSFW but I put it on Page 2 just in case.
