Well Rexo, I'm sorry you had to lose your leg but there are far worse things in life. You now have a chance to fight and have a wonderful, pain free life. It matters not how long, just how good it is. Recovery can be a little difficult at first but once they get the hang of it then there's no holding them back. Rexo is a strong boy and he'll get through this as long you are right there with him. Good luck, buddy; we're here for you.

He even jumped and put his front paw on the counter because he smelled some food.  I'm so proud of him.

Good boy, Rexo!  Livin' the dream!  Ain't it grand to be able to be proud of our dogs for figuring out simply how to be themselves again - even their naughty self?  My first real sigh of relief with Yoda was when he chased a fly all around the house, which was a week post amputation, I think.  Then there was the park visit where he found a dog he could mount, when I had thought that embarrassing behavior was gone for good.  (He basically mounted the air above an oblivious Corgi mix, so maybe it doesn't count).  The next big triumph that I waited and waited for was when he was when he re-learned how to chase his tail on three legs.  Took him 3 months.  He had relearned everything else so fast, I wasn't expecting I'd ever seem him go after that tail again.  I just know I posted my excitement after, haha.  So sooooooo proud!

Wishing Rexo many more such victories!
