QuestionWhy is it important for a pet to have a pet door?
AnswerHi, Brad.
Thanks for contacting me.
A pet door is only "important" if the dog is left alone in the house, and needs to get outside on its own when it has to go to the bathroom. Mostly the pet door is a convenience for the owner, it's not necessarily that important for the dog.
I hope this helps,
