We use the cheap kneehigh panty hose you get in
those bubblegum type containers at walmart, put them on (just like a girl,
hehe) and vet wrap/duck tape it loose around the cannon to keep it from sliding
down. Lets the air in and keeps flies and dirt out. One kneehigh lasts
about one day. If he does walk threw it, it doesn't hurt anything.
But it helps keep it from getting reinfected while it heals. Not to
mention the kids think is a wonderful fashion statement. Skipper
prefers purple. He always looks good in purple.
