I too have a Golden. You want to talk hotspots????

Right now I am treating 2 of them, one on each back leg, on the inside. I clip the hair short and put Sulfodene on them. It does work. One time she had one so bad that my DD called me when she got home from school and asked me what was wrong with the dog. I told her nothing. Well, she had this TERRIBLY smelly, thick pus draining from her ear clear down her neck. Now she was totally fine when I left for work that morning. I was sure she had a horrible ear infection, you know, like maybe the eardrum busted and pus was running out. I took her to the vet the next day. Lo and behold, a hotspot, right under her ear. A big sucker. I never saw it coming.
Hotspots come from irritation. I think my dog's problem is sensitive skin, she has no fleas, is kept clean, etc. I does seem like Goldens tend to be afflicted with this quite often, at least that is what I was told.
Give your Golden a pat on the head for me!!!!!
