i LOVE vetwrap. it's kinda like stick-to-itself gauze. i buy mine at the local feed [horse] store but have seen it starting to get marketed to people in the first aid section.
i also LOVE bitter apple spray. when Holi stepped in a nest of fire ants and got a huge abcess on her foot, i wrapped it with vetwrap then watched her tear it off
. so i wrapped it again and sprayed it; she left it alone
. you can mix vinegar/water or cayenned pepper/water to spray on it. you can also try that stuff people put on their nails to stop chewing on them. it's a bit more expensive but should get him to leave it alone.
you both injured your right? would that be ... 2 hearts as 1? hee hee.
lame, i know.
