Bests & Worsts Reviews from Amazon

We took a shot on this one for our older golden retriever. The only drawback was the training of the dog to use it. In reality, it took only a few days to get him fully autonomous. I think he had figured it out much earlier, but pretended not to do he could keep receiving the treats. He also wouldn't do it on his own for a couple days. He would go to the door and wait to go in our out until we told him. The only negative is the sizing on the larger end. Our dog is about 90 lbs and the door is a bit of a tight fit. For him to get through without banging or dragging the sides, he needs to go very slow. I mean, it works, but even I see if we had gone with the XL door, that unit is only TALLER. I wish they made a size that was just a bit wider. Use the measuring guide and you should be ok. My dog is actually about exactly at or maybe a half inch wider than the width of the L door and it works...but not without a little bit of tightness (which also makes the door get a bit hairy as it works like a brush in his fur when he squeezes through) All in all, we love it. -one caveat: it defintiley cuts down the interaction with your dog. We finally got it because kids are in high school now and with sports and school and activities, we are never sure who is going to be home when. This solved that problem for sure! BUT, on a busy day, the dog coming over and getting your attention to go outside, or barking at the door and coming in happy to see you...that kind of goes away. Now that the dog and the children are all independent, you realize if they don't need something from you, they pretty much ignore you. It does take a way a little bit of relationship time. On the other hand, since this door has gone in and the kids have their drivers license, I get a lot more done around the house. (And by that, I mean, I don't do anything around the house.)
