What lifts my heart the most, is when my dog cannot make the decision as to head out or stay in. She will lay by the pet door, stick her head and shoulders thru the opening, breathing in the fresh air. All the while her hind section is inside laying on the floor. I just cannot comprehend that this can be comfortable to a elderly dog with arthritis.! In Klink's mind, she has the best of both worlds.
Would I recommend purchasing a pet door? Absolutely. I am not saying this due to the fact that I own a web site that sells pet doors. I am saying this because I have observed first hand a whole new side to my dog. A side that I love to see. A side that show's me, even with given a choice, she still chooses to stay close to my side. I sure love that dog!
