My most sensitive child is the one who loves animals the most. I think he bonds with them like friends because he makes so few. I would suggest if you do not have a dog yourself maybe she walk someone's dog if your reason for activity is not to socialize her. My son is very excited to sign up for the volunteer class at our local shelter so that he can start walking dogs there. This is a great ways to stay moving but he's so excited to just be near the animals. Hiking is also something he enjoys, again for the peace and the time to think.
