We have left Leo, our 5 year old spaniel mix, alone for up to 5 hours. We have a routine. Before we leave him, we take him for a trip to the dog-park where he retrieves his Piggy toy until he's tired and had enough, as shown by his standing by the door to leave whatever dog park we're in. This is about half an hour to hour. We take him back to the trailer, leave him a bit of food and lots of water, turn on the AC with the fan running constantly and the radio, and leave open a roof vent or two. When we return he's usually where we left him... on the couch under the Murphy bed. He jumps up, well rested and wants to go to the dog park again. We've asked neighbors to tell us if there is any barking. As far as we know, the only time he barked is when a neighbor's dog came sniffing around our trailer because it escaped its leash. That got Leo riled up. Yes, we lock the door. No we don't have a camera or monitoring equipment. We leave him his toys of course. We do put the toilet paper and wastebasket out of reach, but we have to do that at home too. Leo's a very melo traveling dude who will endlessly sleep on the truck's back seat, as we drive from state to state.
