I had an Irish Setter that used to lick and scratch that same spot many years ago. I spent lots of money at the vet to no avail.One day an old lady asked me why I didnt do something for the dogs' problem.I told her that I had been to the vet several times and had spent lots of money. She said "Heck, dont those vets no nuthin'?All you have to do is rub Bag Balm on it." Well I didn't know what bag balm was and she explained that it was an ointment to put on milking cows teats to keep them from getting raw.I tried it and it worked right away.The dog would occasionly start bothering that area for the rest of his life and I would rub bag balm on it and he would leave it alone immediately.They usually sell it at Rite Aide and CVS.And of course at feed stores.One can for about $8 should last the rest of the dogs life.
