Okay, so you decided that you wanted to get a dog door for your pooch, but should you? Or, do you know which type to get? These are just a couple of questions that dog owners, like you, have. Knowing what types of dog doors are out there and also when your dog wants to go outside are just a couple of things that you need to keep in the back of your mind as you consider them. It is possible and quite normal for dogs to be able to wait up to 8 hours to go outside and use the restroom. However, if you can not be there within those 8 hours, then you may come home to accidents.

Dog doors can be a very wise investment, especially if your dog has never had to wait to go outside before or if they do tend to have a lot of accidents in the house while you are away. A dog door will allow your pooch to be able to go outside whenever he has the itch to head outdoors and you do not have to be home or stop what you are doing to make sure it happens.

Before you choose a dog door, there are some things you need to keep in mind and we will take a look at some of those things now and also provide you with a shortlist of our top recommendations for dog doors.

Do You Plan to Be Home?

One of the first questions you need to ask yourself before you purchase a dog door is whether or not you will be home when they use it. The reason this matters is because you will need to keep in mind their habits, the neighbourhood you live in, and where the door is placed.

For example, if you live on a street that is busy, then you may find that it is not ideal for you to have a dog door that is accessed when you are not home. You do not want your dog to head outdoors and spend the day barking at everyone that strolls by. In this type of a situation, you would need a door that can be easily controlled, when needed.

What Size is Right?

The next thing you need to think about is what size dog door you will need for your home. Do you have a tea-cup dog like a Morkie or an oversized dog? You may find it difficult to find a large dog door, so you must keep this in mind as you shop. If you have a smaller to medium dog, then you can look at dog doors that are medium in size and it will provide them with plenty of room.

As you think about the correct size, you should measure around your pooch’s head and take into account their height and width. This way, you can choose a door that will fit his or her measurements. While you may measure your dog when he or she is a puppy, do keep in mind that you may need a bigger door later on down the road once your dog is full-grown.

Types of Dog Doors Available

There are many different types of dog doors that are available, but we will only focus on the two main types, as this is likely what you will find at the store and what you will want for your dog. You will also want to take into consideration what type of door they are going in into. Is it going to be a patio dog door or a UPVC dog flap? If it is, then you might need someone to come out and fit it, or buy a patio door with a dog flap already in.

Traditional Flap Door

This is the most basic and traditional option out there and likely the one you think of when someone mentions a dog door. This door has a flap that is easy for your dog to push in and out to get into and out of your home.

Electronic Dog Door/Microchip Dog Door

The electronic dog door is extremely convenient and one that operates with a chip that is placed in your dog’s collar. When your dog is nearby, the door opens and allows him in or out. When the collar is off, the door will not work just because your pooch approaches, which is a nice feature.
