Pet Door Solutions for Large & Giant Dog Breeds

Pet Door Solutions for Large and Giant Dog Breeds

Many traditional pet doors are designed for small or medium-sized pets and rely on rigid flaps or fixed openings. For large and giant dog breeds, these designs often create serious limitations.

Large dogs such as Great Danes, Mastiffs, German Shepherds, Huskies, and similar breeds may struggle to fit through flap-style pet doors or may be completely unable to use them safely.

Why traditional pet doors don’t work for large dogs

• Fixed flap sizes limit access

• Dogs must squeeze through narrow openings

• Inserts permanently reduce doorway width

• Large pets may avoid or damage flap doors

How SmartSlydr works for large dogs

SmartSlydr automates your existing sliding glass door instead of inserting a flap. The door opens to a customizable width, allowing large dogs to walk through naturally without squeezing or discomfort.

Because there is no physical flap, pets are not restricted by size or forced to push through an opening.

Who this solution is best for

• Large and giant dog breeds

• Homes with sliding glass or patio doors

• Owners who want pet access without permanent door modification

Common questions
