Oh, and because it came up earlier - he LOVES his Back on Track coat. Obviously I have no idea if it is healing him or he's healing himself, but he practically begs to have it put on at night. This is a dog I have to wrangle to get into his winter coats for walks. I wanted to let him and Meg share it, so since he's sleeping in it, I went to put it on her after dinner one night. As soon as he saw me with it, he squeezed in between me and Meg and sat perfectly still, waiting for his coat.
Also thinking about trying some laser on Zen after he's cleared by my vet. The only vet who does laser around here is 2.5 hours one way. It might be worth a couple of treatments though, if he thinks it'll help. So many people swear by laser that I figure it can't hurt.
PS- I can't believe Gusto and Meg can share the coat. I always though Meg had a good couple of inches on him. He must be taller than he looks in his pictures, or else Meg is smaller.
