Blu-Kote is magical stuff!!
Yes, if you have animals you get to play vet all the time. I got a medi kit from the gun show so I can do stitches if I have to. even have my own scalpel!!
Luckily it hasn't happened. My vet doesn't even insist I bring em in for small abscesses, I can do the shaving & administer antibiotics, the goat pepto & all shots for everyone. The only thing I do have to bring em in for is neutering, broken bones,rabies shot or something I can't figure out from the environment & symptoms. Goats are funny little (??) animals. Chevy thinks he is a people, is happiest out with us, will lie down next to your chair (after drinking your drink & eating all the chips...)
Hope your dog is ok, I know how we worry if they change their usual routine. Jody
