My lab/golden retriever mix had his left front leg amputated on May 3. He has been home for one week. He was just starting to get around well and we saw a glimmer of our dog until May 10. When we brought him home, he had severe bruising all on the underside of his belly from his neck all the way down his body and he had a lot of swelling. The vet said the swelling and bruising was much more severe than she had ever seen. They ran a lot of tests to ensure there was no internal bleeding before they let him come home. They said they thought the bruising was from a fall he took his first day on three legs. 

We have been hot/cold packing everything and the bruise itself seems to be better, however, on Tuesday, his urine was a very dark brown and the swelling has moved down to one of his back legs, causing him to have difficulty walking. He also will periodically  yelp out in pain and look toward his daddy part area.  After many more dollars and many  more tests yesterday, the vet tells us they really aren't sure what the problem is. They think his body is re-absorbing the blood from the bruise, which is causing the dark urine and the pain but they also said this never happens in dogs. very frustrating. 

Today, his urine is a more normal color, but he can barely move. He is on a new medication that causes drowsiness, but we can't even get him to stand up to go outside. Does anyone have any insight to this? It is so heartbreaking to see him like this. He was progressing so well and now we are worse off than we were before the amputation. He is still on pain meds and an antibiotic and this new med that I think is another type of pain medication, but i can't remember the name right now. Has anyone else experienced this situation?
