I have a little 7 month pitbull that I rescued at the beginning of May from a bad situation.  Hugo had a little deformed left front leg that was curled up like a hotwing (we called him Hugo Hotwing).  We had planned on an amputation, but before we could schedule it, he was running around and broke his little hotwing.  We decided to amputate the next day (last Wednesday) since he was already cruising on three legs and the vet didn't think it would be a hardship for him.  He was a rock star coming out of surgery and I had to leash him to keep him from overdoing it at 100mph, and then on Sunday he started walking funny on his back left leg and sticking it out to the side a bit.  The next day he started walking very crooked and veering to the right constantly and his hips shifted so that the right hip is now a few obvious inches below the other.  He's become very unsteady on his feet and has fallen down a few times (this has never happened before to him…).  He no longer wants to play or engage with our other dog, who he couldn't keep away from before.  He still has a great appetite for food and water, but just goes out the door 5 ft, does his business, and wobbles back inside to lay down and be depressed.  He was on Tramadol, Rimadyl and Cephalexin and the vet told me to discontinue all three on Tuesday evening in case it was a drug thing.  He did not improve and he is now at the vet for tests.  Xrays have showed no abnormalities with his spine, he is still wobbling about and now has a 103.5 fever.  Any ideas on what may have happened?  The vet is stumped for now and is doing blood tests and keeping him for observation.  I'm very scared because I love my little man!  Hs this come up with anyone else's dogs?  Will he get back to his normal wacky self?

We met someone in the waiting area of the vet hospital whose dog had a stroke after surgery.  The symptoms he described sounded like what you are describing.  That might be something to inquire about with your vet.

hope you find the answer soon and he is back to normal

You are all so nice! Like a family I will never meet!

Well I just heard back from my vet.  All tests for stroke and other neuro disorders have come back negative.  His xrays all came back normal–they only found a very small narrowing between T11/12, but nothing too exciting.  They did check for diskospondylitis (thanks for the heads up Comet dog!) and also for mega-esophagus and other things I could not pronounce.  He is able to walk on his hind legs when he's excited and jump on people (he loves the ladies at the vet!), so the vet thinks that at this point there just may be more compensation for the lopped off hotwing than he thought would happen.  He wants to keep him for two more nights and days so that he is in a very controlled environment, but has done all the tests so far that he and the other vets he's consulted with can think of.  Wants to wait two more weeks and call it the end of his amputation recovery.  Hopefully he is better after that and if not, he says 'specialist-hunting we will go!'

Holy crap!  Comet was one cute puppy!

I can totally see what you're talking about.  Hugo's hip on the left is sticking way up right now too and he straight-legs it to the side.  It was never like that before (when he did have his hotwing), just happened four days after his surgery.  I just visited him at the vet's and he was very happy to see me, and went on a little walk, but didn't want to.  Maybe his brain just needs to snap out of it and get him back on track.  That's what I'm hoping for anyway since tests are all coming up normal so far.  Here's some cute pics of my baby boy…
