Well, we haven't had to worry about a corgi with cuts of any kind for at least 4 years! Lucky has been crippled, and when we rescued Sonny a year ago, he just kinda stayed under the desk for a couple of months and then right with us. Well...he discovered the large rocks on the South side of the front yard a couple months ago and likes to climb them, and he climbs around all over the place now. Today we discover blood on his neck, doessn't appear to be a puncture wound or to have come from his collar. I don't really find a cut, but this afternoon there now appears to be a bump - pus starting to form? Wonderful, it's a holiday weekend. We first thought he got into the cactus, but no pricklies. So my question is, what can I put on it? I am thinking dillute hydrogen pyrioxide is ok, but anything else? I am out of practice! Thanks!
