Lebowski had an ear infection when I first received him, but has been on medication for almost two weeks and is doing much better- he is so much happier now that it's not irritating him! He has also been less snappy and seems to be settling into life with Squunz, my other dog. They are inching closer to full-on puppy cuddles, but sometimes still pretend like they don't care about each other, although I feel like in the next month this will blossom into a doggy bro-mance.
Lebowski's legs are also improving, he's developed more muscle now, so he doesn't trip as often, and two days ago he somehow managed to climb up some stairs -then got stuck and couldn't get down- but that fact that he made it in one direction is encouraging. I feel like in a year he will probably look and act like a 'normal' dog, and there won't be any evidence of his back surgery.
Once his ear clears up completely I think we will try wading/swimming to help get his back legs stronger, but so far he's been doing great just running around the house. He and Squunz have been getting along so well, I definitely have zero regrets about adding a second dog to my family- Lebowski's hilarious personality has brought so much joy to both mine and Squunz's life. We love him!
