Review on 🐾 PetSafe Plastic Pet Door for Cats and Dogs: Durable, Paintable White Frame with Tinted Vinyl Flap, Easy-to-Install, Indoor/Outdoor Use | Multiple Sizes: Small, Medium, Large, X-Large by Peggy Bui

The size is suitable for a very large dog. Says it can hold dogs up to 200 pounds and our lab is about 90 so there's plenty of room. That's all the good things I can say about this pet door. It's not very strong and after installation we saw several cracks that allowed water to leak out. It was necessary to cover the entire outside of the door with silicone to prevent rainwater from entering. The worst thing is that the lid is completely unusable. It doesn't stay attached to the frame, and even a little push from our lab and it's in. We've even tried gluing the lid on for extra support, but it's no use. We had to put a lid on the inside to keep intruders out when we were away, but if he could open it, anyone could. The problem now is that we have a very big hole in our door. So if we replace it with another model, we will most likely have to replace the entire door.
