Dog Flap: Frequently asked questions

What types of Dog Flap are there and what determines a good product?

There are a few different types of dog flaps available. The most common is the magnetic flap, which has magnets that attract and hold the door closed when it’s shut. Another type is called an electronic pet door or electric dog doors, which use electricity to open and close your pet’s access point into your home. These can be either wired in with electrical wiring or run on batteries for convenience purposes (which means you don’t have to worry about wires). Lastly there’s manual flaps as well but these aren’t very popular anymore because they’re more difficult to install than other options so we won’t go over them here.

It’s all about the design. The more secure your dog flap is, the better it will be for you and your pet. A good quality door should have a lockable latch to prevent unwanted entry from other animals or children as well as an adjustable collar that can fit any size of dog so they feel comfortable going in and out without getting stuck.

Who should use a Dog Flap?

Dog Flaps are ideal for households with multiple dogs. They can also be used by anyone who wants to give their dog access into the house without having to let them in and out all day long. If you have a puppy or an older dog that has trouble jumping, then installing a flap is essential so they don’t hurt themselves trying to get through your door every time it opens.

Based on what criteria should you buy a Dog Flap?

The most important factor to consider is the size of your dog. If you have a small breed, then any flap will do but if you have a large breed or multiple dogs that are big and strong, it’s best to buy one with more security features like double locking mechanisms. Another thing to look for is weatherproofing as some flaps can be damaged by rain and snow so make sure yours has this feature too before buying it. Also, check out how easy they are to install because not all models come with instructions on how exactly they should be installed properly so read up on reviews from other users first before making your final decision.

There are many things to look out for when comparing a Dog Flap. You need to check the quality of materials used in making it, and whether or not they will be able to withstand your dog’s strength. Also, you should make sure that there is enough space between the flap and frame so that your pet can easily get through without any problems. The size of the door also matters as well because if it is too small then even smaller dogs may have trouble getting inside while larger ones might end up breaking it down.

What are the advantages and disadvantages of a Dog Flap?


Dog Flaps are a great way to allow your dog access into the house without having to worry about them getting out. They can be installed in an existing door or wall, and they come with many different features that make it easy for you and your pet to use. Some of these include voice activation so you don’t have to get up every time Fido wants inside, as well as locking mechanisms that keep him from going outside when he shouldn’t be allowed outside at all times. These flaps also help prevent drafts from coming through doors during cold weather months by sealing off any gaps between the flap itself and the frame around it.


The main disadvantage of a dog flap is that it allows your pet to come and go as they please. This can be dangerous for them if you live in an area where there are lots of other animals or people who may harm them. It also means that the door will need to stay open which could lead to draughts, cold weather etc… Another problem with this type of door is that some dogs don’t understand how it works so they just push their nose through the hole instead.
