Dog doors and gates will keep your dog safe, as well as other people and your belongings.
Things to consider: Safe installation, locks, and objects in the house that are accessible to your pet.
Safety First - Safety is key when setting up dog doors and gates. The last thing you want is for a dog gate to collapse on top of your dog or a dog door to be installed too low that your dog has to stoop down and crawl to get through it.
Dog Locks - For total home safety and security consider adding a dead bolt lock to go on your dog doors and gates to the outside.
Puppy-Proof - When there are low-lying objects all over your house that your dog could get into while you are not home, dog gates that limit your dog's accessibility all but the "puppy-proofed" parts of your house are essential for your dog's safety.
