I recently purchased a one year old male bluetick (been here 1 1/2 weeks) and he has developed a spot in the last day or so about 1.5" by 4" where the hair fell of on his front shoulder. The skin where the hair fell of is infected looking with slight drainage. There is no sign of injury, insect bite, or snake bite. He has been in the kennel the whole time he was here. The surrounding skin where hair is still present also shows some sign of like bumps or infected hair follicles. He drinks well, eats well, plays, and shows no sign of sickness. I have been cleaning it with rubbing alcohol, hydrogen peroxide, and then treating the are with Betadine solution. Any ideas what this might be?
