Independence matters to dogs of all ages — but for senior dogs who may need to go outside more frequently due to reduced bladder control, a dog door can be genuinely life-changing. It eliminates the anxiety of waiting to be let out, reduces house soiling accidents, and gives your senior dog the dignity of managing their own toileting needs. A good dog door also means you do not need to interrupt your day every time your senior dog needs to go outside.

How to Measure Your Dog for a Dog Door
Measure your dog’s width at the widest point — usually the shoulders — and add at least 5cm on each side. Measure your dog’s height from the floor to the top of their back and add 5cm. The step-over height — the distance from the floor to the bottom of the flap opening — should be low enough for your senior dog to step over comfortably. For arthritic dogs the lower the step-over the better.
Training Your Senior Dog to Use a Dog Door
Some senior dogs — particularly those with cognitive decline — may need patient introduction to a new dog door. Start by propping the flap open and encouraging your dog through with treats. Gradually lower the flap over several days until your dog is confidently pushing through it on their own. Never force your dog through — patience and positive reinforcement are essential.
Frequently Asked Questions
Will a dog door let cold air in?
All dog doors allow some draught — a rigid flap like the Staywell minimises this significantly compared to flexible flap designs. For senior dogs who feel the cold more, consider placing the dog door in a sheltered location and using a draught excluder around the frame.
Are dog doors a security risk?
Medium and small dog doors are generally too small for a person to access. The closure panel on the Staywell allows you to lock the door at night or when away from home for extended periods.
Our Verdict
For senior dogs with reduced bladder control or those who need frequent outdoor access, the PetSafe Staywell dog door is a practical and reliable solution that gives your dog independence while giving you convenience. A simple installation that can significantly improve quality of life for both you and your senior dog.
