One of my travel buddies has 6 dogs that live inside their house. Whenever we would go out of town she would hire someone to take care of her dogs. Her husband is our usual driver so no one is left at home to tend the dogs. Their home is in the suburbs so it is not easy to find someone for the chore of taking care of her pets. There were time that she would not go with us because of that issue. My suggestion is to hire a regular maid for that chore so that the maid would be used to the dogs and vice versa.
