Locking Dog Doors

Explore locking dog doors from Closer Pets, a convenient way for your dog to spend time outside without the fear of uninvited visitors. Dog flaps allow your pup the freedom to toilet or visit their outdoor area whenever they wish, which can be highly convenient for you and your dog alike.

With dog flaps comes the opportunity for neighbouring pets to come visiting or worse. Which is where a locking dog flap comes in useful. The idea is to give your dog the freedom to explore and use the garden while minimising the chances of unwelcome visitors.

What's more, you'll get FREE standard delivery on orders over £39! (Excluding islands)

To help you decide which dog door is right for you, take a look at our pet door guide, with advice for different sizes of pets, door materials, and any pet door accessories needed.
