Large Dog Flap Closer Pets Dog Mate White 216W
Product Description
Dog Mate 216 Large Dog Door White With Clear Flap
Give your dog the freedom to come and go with the Dog Mate 216 Large Dog Door in White. Designed for Labradors, German Shepherds, Golden Retrievers and other large dog breeds, the Dog Mate 216 combines a generous opening with strong construction, a clear weather-resistant flap and a removable locking panel.
As one of the largest pet doors in the Dog Mate range, it is an excellent choice when a conventional dog flap simply isn't big enough. The generous opening is suitable for dogs up to approximately 630mm (25") shoulder height, although we always recommend measuring your individual dog before ordering.

Large Dog Door for Labradors, German Shepherds & Retrievers
The Dog Mate 216 has been designed to provide comfortable access for many larger dogs. Its spacious opening makes it suitable for breeds such as:
- Labrador Retrievers
- German Shepherds
- Golden Retrievers
- Boxers
- Weimaraners
- Large Spaniels
- Similar large dog breeds
Breed should only be used as a guide because individual dogs vary considerably in height and build. Measure your dog before ordering and compare their shoulder height and body width with the opening dimensions.
Clear Weather-Resistant Flap
The flexible transparent flap allows your dog to see through the opening before passing through it. This can be particularly helpful when introducing a dog to a pet door for the first time.
The flap is designed for smooth, quiet everyday operation while helping reduce draughts and exposure to poor weather.
Strong Locking Panel Included
The Dog Mate 216 is supplied with a removable locking panel which can be fitted when you don't want the dog door to be used.
This is useful overnight, when you're away from home or whenever you need to restrict your dog's access through the door.
Please note: A pet door should not be considered a substitute for normal household security. Because of the size of this opening, appropriate additional security measures should always be considered.
Self-Lining Design Up to 50mm
The Dog Mate 216 features a self-lining frame for installations up to approximately 50mm (2") thick. This creates a much neater finished opening through suitable doors and panels.
Depending on the construction of the property, the Dog Mate 216 can be used for installations including:
- Timber doors
- Suitable uPVC door panels
- PVC panels
- Conservatory panels
- Suitable composite panels
- Wall installations with an appropriately constructed tunnel
Always check the construction of a door before cutting it. Reinforced doors, composite doors and glazed units may require specialist installation.

Measure Your Dog Before Ordering
Choosing a dog door by breed alone can result in buying the wrong size. Two Labradors, for example, can have very different body dimensions.
Before ordering, check:
- Shoulder Height – Measure from the floor to the top of your dog's shoulders.
- Body Width – Measure the widest part of your dog's body.
- Installation Height – Position the opening so your dog can pass through comfortably without having to jump or crouch excessively.
If you're unsure whether the Dog Mate 216 is large enough for your dog, contact CatFlaps.co.uk before ordering and we'll be happy to help.
Replacement Dog Mate 216 Flaps Available
One of the advantages of the Dog Mate 216 is that you don't necessarily need to replace the complete dog door if the flap becomes damaged through years of use.
