Make sure you talk to your veterinarian as well as your physician to make sure you are both healthy enough for yoga. While you are able to tell the doctor when things are bothering you, your dog cannot do that. So, you have to watch for those subtle signs that he may be overdoing it. If he is not up to doga, let him sit and watch. If either one of you has any kind of physical conditions that could make exercise a problem, make sure you take it easy and stay in tune with your body.
