I rescued a Dalmation mix puppy and about a week after bringing her home, shes developed what looks like tiny red pimples on her stomach and armpits. I took her to the vet and the vet didn’t seem worried. She said to spray her with antifungal and antibacterial spray. However, it itchiness stops for about an hour and then shes right back at it again. Does anyone elses dog have this problem?
