Yesterday, I loaded Naners on the trailer and off we went for our lesson. She was quieter than usual, no banging at every stop sign and light (she doesn't kick, she just moves around and since the trailer is steel it makes a lot of noise.) We've been trailering a lot lately, so she's probably just gotten more tolerant of the situation (it happens. She's always bad for a bit, then gets better) We got to the trainers and I unloaded her and she stepped off so quietly, when she usually leaps. Unfortunately, she stepped off so quietly she didn't quite leave enough room for her hind legs to come down and she scraped them against the little bits of metal that hold the corners of the bottoms of the double doors. What originally looked like a surface scrape was not:

That's what it looked like after the vet had snipped off a flap of skin. There was also a pretty deep puncture that extends about an inch down from the hole, discovered when she was flushing it with saline and the skin was extending outward as the saline went in. I'm really, really glad I called the vet.
Naners is now laid up for goodness knows how long. Depends on how things go of course. Going to the rally is out, so we won't be able to qualify for PC Champs. I get to practice my fine wound wrapping skills again. I still have supplies from last summer.
Obviously, I don't wrap when we travel. She wears bell boots when I can get them on her safely (as soon as she realizes she has to get on the trailer she starts carrying on.) I've been thinking of ways to make the back of the trailer safer, there isn't a way to pad the things in a way that the doors will still be able to close. A neighbor/friend thinks we could at least take the corners off the holder thingies, which would make it quite a bit better. I shall post before and after pics when we do it, as my trailer is not the only one out there with doors like this.
