We have a chihuahua and a cocker. The cocker is overly friendly, the chihuahua will warm up to you. Does not always react well at first to men. They have a doggy door.. but need a walk a day or so if weather is nice. Food will need refilled. They are on autopilot ...they prefer someone in the home,, (at least I think they do). We have had house sitters before and the dogs like to sleep with warm bodies.
