If its itch (queensland/summer itch) I gave this new stuff a try called Thoroughbred Fix. My terrier had it on his back, no fur left, and it fixed him in about 5 days, even the hair grew back in about 10 days. I've never seen anything work so quick, just to double check I let my neighbour try it on their border collie and it did the same thing. Works well at healing the bites and wounds as well. A good tip from the makers is to spray the bedding area and any haunts your dog has with a dilution of the treatment as well, their theory is a lot of the skin problems are fungal and the fungus will just come back if you don't get all the sources. I've seen it work and it does work well. Worth a try.
