I think therapeutic puppy rentals could be a great sideline business for breeders. They could even have a playroom with toys, etc. plus beverages for the adults for people who just want to relax with a puppy (or kitten) for an hour.
red fox labrador retriever from Oakdale labs - Eli the Gray, he is an absolute terror. Ate three pairs of shoes, destroyed my potted plants, 1 & 2 on my pottery barn seagrass rugs! His only redeeming quality is that he takes cute photos!
