I wanted to let you know of this wound spray I tried on my dog. It is called Vetericyn and it doesn't need a prescription. My border collie Chance had a hot spot on his back and I started to use this product. I sprayed it on his hot spot and in less than a week it was completely healed! This product works great! It can also be used on horses for cuts, cinch rot, ear and eye infections and rashes!
