As it says on the Pawz site, Penny was fine about wearing the boot. (We've had it on a couple of times in the kitchen, accompanied by treats, to help her see it as a positive experience.) However, walking on the rocky hillside seemed to hurt her foot and she really wanted to lick it! But she was easily distracted.
I'd vote the shoe a success. The reason we were keen to try it was that we're going to Brighton Beach tomorrow and I don't like the idea of sand getting into her surgery scar.
When I picked the shoes up, from Melbourne Veterinary Specialists, I was told to stretch the top of the shoe for a couple of hours, just to make sure it's not too tight around her leg. I stretched it on the top of a small glass jar.
