You & your family did the best for her. Not every dog is a wheel chair dog. My great grandmother was forced into a wheelchair after a drunk driver hit her.. She was NEVER happy again, she was American Indian & use to walking & hiking everywhere.. taking away her ability to walk destroyed her till the say she died. I could never put a high energy dog in a wheel chair either, it would be hell for that dog.

Just remember that Tango can play with her brother now & they will keep each other company at the Rainbow Bridge, until its your time to claim Tango once again.
