Night before last I noticed that Shyla had two sores on her back about the size of a quarter. She does not like me to touch them but other than that she is fine. I have not changed her food or anything else. I gave her a bath that night and did not notice them when I was bathing her but an hour later I felt them and they were hard feeling. Possibly they were there the whole time and I just did not feel them. I bathed her with the same puppy shampoo I have always used. They feel hard but you cannot see them just by looking at her. One is on her lower back and the other is between her shoulder blades. Possibly they are mosquito bites that are in bad shape? We have tons of mosquitos due to heavy rains. I'm really just wondering what I can put on them? Hydrocortisone? Antibiotic ointment?
