Coban, hydrogen peroxide, neomycin ointment and drops, hurricaine gel, and benzocaine are also good to have on hand.
I've also used DMSO for an analgesic and anti-inflammatory. It works!
I used to use dmso on one of my goats that had problems with her 2 front legs...somedays I’d see her walking on her front knees (don’t know why) but would dab dmso on the knees and soon she would be up walking on all four...the trick is not to rub it into the area, just dab it a couple of times. (at least with goats, those that used it said never to rub it into the skin)
