Well, if you get really desperate (and the basket muzzle idea doesn’t work–that’s a neat idea) you can always go old skool and use a bucket. You’ll have to get a bucket that is longer than their head is long (their muzzle cannot poke out the end), then you cut a hole big enough to pass their head in the base, and punch a few holes around the base. Put bucket on dog like a cone o shame, thread shoelaces through the little holes and tie to the collar.
When I was a kid, we had to do this when my first dog was spayed. She was SMART with the cone–she lied down next to the sofa so the cone curled in, and then chewed it off.
Hang in there. This part sucks! :lol:
(FWIW, too, I’ve dressed animals with non-flush staples and never had them pull out or catch. In one case, I put a wee little dog coat on a CAT, because she had staples right over her withers and I didn’t want her yanking them if she scratched. Worked great!)
