Can a dog stay in a wheelchair all day?
This often depends on the age and overall stamina of the dog. It's safe to say anywhere from 15 minutes to an hour. Start out with shorter periods of time as often throughout the day as your schedule permits. PLEASE DO NOT leave your dog in his or her wheelchair unattended for any length of time.
