Two people from my group had post amputation issues over the last few months. One had the remaining leg swell up to the point of not being able to walk on it. The vets in the specialty hospital were not even sure what was going on. He was home a few days after amp, and was back in the hospital for two weeks.he is fine now, happily hopping about with no issues.
The other had a more typical infection like what you describe. That one was in and out of the hospital, but is also fine and happy now.
Both these moms expressed the same feelings that you are experiencing. Did I do the right thing? How could I have done this to him? Should I just go yank him out of there? Will I get my boy back? Will he have any quality of life? Both these dogs are twelve, which added to the guilt of not just bringing him home to live out what time he had left instead of amputating the leg.
Sometimes these things happen. I'm sorry to hear that you are going through this. Amputation is major surgery, and there may or may not be complications. Stay in touch with your vet. Know what they are doing and why. Get another opinion if you need to. The two dogs I mentioned are leading happy lives now. Make sure that you have your own supports to get you through this. I hope you have a good outcome after this bump in the road. We never know which dog will walk out of the hospital with no problems after the surgery. We all hope that our dogs can do it that way, but it is out of our control. Don't look back! Second guessing will just make you feel worse.
Hope this resolves soon. Hugs!
Just wanted to add that both these dogs were at a very well respected specialty hospital with tons of greyhound experience. One of these moms also asked if she should just yank him out of there, take him someplace else, or put him down. That was grief, fear and guilt talking. If you have real doubts about the hospital's ability to provide quality care, then consider moving him, but the new place will have to play catch up! If your reaction is out of guilt, frustration, panic, and fear, just get more involved in the decisions about his care. More hugs!
