I've been walking and sitting for friends dog when they go out of town. I believe I get more from the pet then I give. When they sense their going for a walk they get excited so both of us get out in the sunshine, get exercise discover the out doors. A dog who is walked and given different surrounds in a very happy relaxed dog. Dog are very social animals so having an "extended member of the family/pack" to go for that extra walk or just a visit can make a dog's day I adjust for the dog's needs and that of its family. I follow instruction given so the dog routine is maintained and treat the pet as if I was my own.
