I have 2 small dogs of my own that love to run and play with other dogs. I walk them twice a day, and take them to a large fenced park in the evening, when it is not so hot during the day. For house sitting, I will spoil your dog to no end and treat them like my own. It is up to the home owner if it is ok to bring my dogs. For Boarding, I know my dogs. I have a small Maltese that doesnt like puppies or bigger dogs unless 7 yrs and older. I will keep him away from any puppies or dogs he could get aggressive with. You wont need to worry. I will love your dog like mine.
