We adopted a dog once in the same circunstances, but when we brought him home it was way to hyper and crazy and it just didn't work for us. What we ended up doing is taking him back to the shelter and sponsor him until he got a home ( I didn't want him put to sleep).

We gave it another shot with another dog, and went through the same. It was a beagle and our pretty big back yard wasn't big enough. This time, instead of taking him back to the shelter, we put an add in the paper. We found a old couple who had had a beagle that died from cancer and were very sad. We sent to see them with "buttons" our dog and found they were a perfect match so we let them have it. We visited buttons a few times to make sure he was ok.

Good luck with your new addition to the family.
