The Best Dog Doors

The beauty of a dog door is simple: it allows your pup access to the outdoors without you having to physically take part in bringing your dog and and out. Don't get us wrong; one of the best parts of sharing a life with a dog is romping about outside together. However, on days where you're out of time or you dog just wants to lay outside in the sunshine, it can be a wonderful thing to have a dog door. Choosing a dog door requires knowledge on safety, size, fit, and ease-of-use (as well as durability--your dog will likely be running in and out multiple times a day). These top 5 contenders for the best dog door make that choice a simple one.

Frequently Asked Questions

Do dog doors allow wild animals to enter the house?

While yes, dog doors do have the unfortunate risk of allowing wild animals indoors, this does not typically happen. Wild animals tend to prefer to stay in the wild, and especially so if they smell the scent of humans and dogs at the threshold of a dog door. Most dog doors also have a locking system that allows you to control access. Thus, when the door is not in use, you can lock it, effectively keeping unwanted critters out.

Are dog doors burglar-proof?

If you have an alarm system installed in your house, a dog door will not lessen the security of your home. Furthermore, having a dog means that would-be break-ins are much less likely to occur: the sound of a barking dog is a fantastic deterrent to any burglars.
