Review on PetSafe Selective SmartDoor Automatic Programmable by Karen Cooper

I bought this door for my Great Dane and to keep my cats. It serves its purpose. But there are a few problems I'm trying to solve. Button programming was a bit tricky to find the right sensitivity. This large door is suitable for medium-sized dogs. I want it to come in XL. My biggest complaint so far is the loud clicking sound every time it unlocks. This scares my dog and he refuses to go through with it. She would rather bark in the street all night than walk to the door and be startled by a clicking lock. I need to work on desensitizing her. I will post an update in a few months
