It's a great first aid spray that is advertised mostly for oral problems but, My grandma used it for everything and I do too. I've used it on my dogs hot spots, campfire burns, scrapes, cuts ..like I said just about everything. Merlins scrotum got raw last fall and he really objected to the nustock so I tried spraying it on then letting it dry and then applying the nustock and it was fine. He healed up pretty quickly after. The ingredients are pretty benign but effective...just thought it might help your new boy.
