In reply to veteye:
It was on the brink of retirement, and I was debating whether it was repairable for a bit longer.
We have a new rescue dog who can stretch her paw remarkably far out of the bottom gap in the crate in the van. She reached the jacket and pulled it into the crate, which ripped it beyond all possibility of repair!
So, that was the fate of the jacket decided for me! Thanks hound! (She is a truly lovely dog, but we are her 4th home and she is a year old. There is still a lot of unsettled behaviour which we are working through!)
