Winston, my 6 month old bulldog, has developed a few hard, pimple-like, bumps on his upper and lower back over the past few weeks. They don't seem to bother him when I put pressure on them so I'm not overly concerned. I know he has some allergy issues and have been experimenting with different foods. Currently I have him on Wellness Core - Puppy Blend, which has taken a lot of his skin irritation away and given him a nice soft coat. I posted a photo of the largest bump in hopes some of you may find them familiar. He is my first bulldog so I'm not too familiar with all of the common skin and allergy problems that these guys can have. Any insight on what these bumps may be is greatly appreciated. From what I can determine, they might be hives due to his allergies??
