Many customers search for their dog doors by size such as small, medium, large, extra large and big!  However, even though America's Pet Store has provided a breakout of its big dog doors for your shopping convenience, we recommend that you measure your dog for a proper fit prior to purchasing a dog door. If you would like details on how to measure your dog please call our doggie door experts in Customer Service at 800-870-1941 or see How to Measure Your Dog For a Pet Door.

The reason why measuring your dog is so important prior to purchasing your big dog door is because all manufacturers define their sizes in very different ways.  There is a wide range of dog door widths and heights that make up the category of big dog doors.   Why is weight not a good proxy for your dog door size?  Well, an English bulldog and Afghan hound weigh about the same amount, but I can guarantee you that they would not use the same size dog door. 

The good news is that most of today's top manufacturers of dog doors have included big dog doors in their line-ups. You can find automatic dog doors, electric dog doors and infrared dog doors in large sizes. Even patio dog doors come in sizes big enough for large dogs. Sliding glass dog doors are made for either aluminum sliders or vinyl sliders such as Pella or Andersen brands. However, a word of caution: patio door dog doors must specify that they are compatible with vinyl sliders. If not specified, assume they will not work with vinyl sliders.

Maybe you are looking for a specific model dog door manufactured by Gun Dog House Door named the Gun Dog Big Dog Pet Door, or the Gun Dog Easy Big Dog Pet Door?  America's Pet Store carries both of these big dog doors.   Gun Dog House Door's standard model, called the Big Dog Pet Door, is manufactured with special heavy-duty spring loaded hinges that provide a strong weather seal.  The one complaint that America's Pet Store receives on this door is that the heavy duty springs produce a loud "bang" when your dog enters or exits the door.  This noise is not problematic in kennels, but might be annoying if installed in a house.  Gun Dog House Door's model, the Easy Big Dog Pet Door is designed for big dogs that are timid, arthritic or old.  It is also a much quieter dog door than the original version of the Gun Dog Door models.   Both models of these big dog doors are chew proof, durable dog doors framed in aluminum.  You can also make your Gun Dog big dog doors more secure by purchasing the optional security panel. 

There's a lot to consider when choosing the perfect door for you, your dog and your home. If you need assistance selecting the correct door out of our lineup of big dog doors, please contact an America's Pet Store customer service representative.
