We are going on vacation and would like to leave our dogs home. We are trying to choose between boarding at our vet, or a paid dog sitter in our home. One dog is a puppy not totally potty trained, the other is 7 yrs old and attached to his home, not a traveler. We do have a doggie door for the older one. My husband thinks if the puppy goes to a boarding place he will become a barker which he is not now, and that he will not be comfortable there at such a young age. Has anyone had any experience with this?
