When the pup had his second jabs at 10 weeks, I pointed out these weird bumps on his belly. She diagnosed puppy pyoderma, and gave us a weeks worth of antibiotics. They didn't seem to bother him and he finished the course. The rash cleared up. Three weeks later, (last Friday evening) I noticed a blister on his tummy, and took him back (last Saturday). By then, he had several large pus filled blisters. Again, puppy pyoderma was diagnosed and now we have 10 days worth of antibiotics. He's very sleepy today, and scratching at his ears a bit. I bathed him in malaseb too, to see if it would soothe him. Has anyone else's pup had this? Did it recur? Can't help worrying about the little guy.
