Thanks for the info! It's encouraging to hear that your dog has made a recovery without surgery.

Marta's surgeries actually worked really well and the total recovery time was only a few months. She's 10.5 and has no pain or problems in her back legs (though I still don't let her do any major jumping). But, I'm afraid that Vallis wouldn't do well because of his previous experience with anesthesia, since after he was neutered he starting having seizures and nearly stopped breathing.

I took a look at the site you gave me, and Vallis' leg has made a lot of improvement over 4 weeks, which is good. He doesn't limp anymore while walking, but it looks like he may need to be restricted for longer than 8 weeks.
