So no pictures today, unfortunately. I've tried taking it apart... basically I've tried everything short of actually getting it professionally repaired, because for that cost, I might as well buy a new one.
Anyway, we're in Sarasota now and it's gorgeous here. We haven't gone to the dog beach yet because I went to Casperson (which is connected and right down the street) and the rip current was pretty intimidating. So we've stuck to the "dry" dog park down the street.
We've made some friends there, including a dog named Lunchbox. We're going to a bay side park this morning, so hopefully the dogs can swim safely there.
I'll post pictures and a training update as soon as I can.
