We have two small dogs (daschunds) and we'd prefer not to board them in a kennel for a long period of time. They are very friendly and when you leave the house, they are crate-trained. These dogs sleep in our bed and that would be expected of the house sitter.
We live in an upscale active adult community which is convenient to shopping. We do NOT want someone who will be away from the dogs for more than four hours at a time.
