Unless your dog needs space restriction, we leave our doggy door open so they can go in and out whenever they want in our private fenced yard. Some dogs will learn the door in no time while others won’t. In the case that they don’t, we’ll let them out every couple of hours. We close the doggy door if we leave the house and have cameras all over the house to check on them. The safety of your dog (and ours) is extremely important to us. If needed, we have a pet den to put your doggies in. We use this pet den if puppies (or adult doggies) need some space restriction, like if they’re not potty trained yet or if they’re chewing on things they’re not supposed to. This is to keep them safe from possibly getting trapped in things or chewing on dangerous things like electrical cords. We rarely have to use this den though, most dogs we watch just hangs with us in the living room, our office and bedroom! Lastly, we keep our house clean and tidy, removing any hazards for dogs.
