We bought one in December. We set it up for Christmas morning for the kids to find and it was a neat surprise for them. I am not sure the material would hold for dog claws but some of the house parts have empty floor areas, so those would be fine. The kids still play with it but not as much as at first. My 2-year-old likes it most. The 5 and 7-year-olds like it too, but more for changing it around and reconfiguring. It takes up a huge amount of space when set up, but it folds up very flat and you can hide it behind or under a couch or something. Also, be careful when you undo them. It comes boxed in a way that makes it seem small but the pieces expand quickly. Nothing dangerous, just surprising if you aren't expecting it.
