I hope that you get a better response than I did when I posted needing help for my best buddy of 14+ years. My dog has had skin problems off and on for the 14+ years that he has lived with me. When I moved to Central Fl - it was more on than off. It finally got so bad that for the better part of 2 years it was a constant battle. Here is the magic combination that finally worked for my baby. #1) I changed his food - he is now on Nutro Ultra Holistic food for Senior dogs. #2) 1 more final round of antibiotics #3) Vet's Best Tea Tree Shampoo and Spray. I initially bought it @ Petsmart - but I don't think that they carry it any more. I finally called the 800# on the bottle and was told that Petco carries it - so every so often I make the pilgrimage to Lakeland to buy it. The difference was immediate when I used that shampoo and spray on him! He stopped chewing and licking immediately, slept better and through the night, and instantly seemed more comfortable. It's in a slender, round, tall green bottle with white label and it's a miracle in a bottle for us. I just wash him with the shampoo, and when he is almost dry I spray him with the spray and rub it in. I spray anything that looks suspicious right away and nothing has gotten out of control since early last December when I found this stuff. Literally - I don't think that he had been comfortable in over 2 years. Every time that we would finish an antibiotic - he would relapse within 2 days of ending the pills. Also - FYI, when he had an infection on his pinkie toe - the vet told me to wash his foot several times a day with Selsun Blue shampoo and told me that it's a really strong anti-fungal.
Good luck! I hope that this helps.
