Glad to hear everything is ok. My Golden Retriever did the same thing, except it was outside. He was jumping on the chainlink fence and almost ripped his dew claw off. Blood everywhere. We took him to the vet and they stitched him up. The vet told me how one of the vet techs passed out trying to clean his wound up. I guess the sight of so much blood and the smell got to her haha....
