There is a stray dog in my area and he has fleas. He scratches the area behind his ears, neck and lower back a lot and he has open wounds now in those areas. He also sometimes bleeds if he over scratches. I was going spray lemon juice water mixture but I'm afraid that would create a burning sensation in the open wounds. I also have a spray for fleas but I'm concerned it will irritate the wounds too.
So is there anything else that won't irritate his open wounds, perhaps even help to heal the wounds, along with getting rid of the fleas?
