This morning I noticed Rugers hair was looked thin & when I pulled on it it all came out & was red underneath almost like a blister, about the size of a 50 cent, I then pulled more hair & there is 3 spots, all on his shoulder. Hot Spots??? H has been rubbing along the couch & was moaning this morning, but that is not unusual for him, LOL He is a DRAMA KING. We do not have a full time vet & I have an appt for Thursday, but everything I read about hot spots says it is usually long hair dogs etc. It has not been that hot, very humid, mid 70's, I use no flea collar, no front line etc. & he has only been in the house for the last 4-5 days. He does have allergies, he can't have a distemper booster, certain foods make him puke, etc. I put hydrocotorzone on it. Any Ideas?? 

Those look like hot spots.  I haven't tried it, but another dog person recommended Chris Christensen's Peace & Kindness for hot spots.  Here is a link: www.chrissystems.com/peace.htm

 It was hot spots, she said I did everything right, clipped the hair put on anti-itch, etc. Thanks everyone!! She said it is probably because he has allergies, but that it was healing good so no antibiotics.
