America's Pet Store offers one of the broadest selections of large pet doors online - all with free ground shipping.
Please measure your dog before ordering to be sure the flap entrance is large enough for your dog to go through. Check out How To Measure Your Pet For a Dog Door to assist you in selecting the ideal size dog door.
It is important to also take note of the overall size of any pet door you purchase. Is the installation area large enough to accommodate the overall size of the dog door you are considering? If you have any questions call the dog door experts in our Customer Service department and they will be happy to assist you.
