My puppy is just 6months old and had earned the right to spend the work day in the kitchen and out of his crate. Things went well on day one. No problems, on Day two the bed which we have had since he joined our family at 10 weeks was unzipped and the bumper portion filler was completely removed from the bottom. Also the pillow was unzipped but I guess he could not figure out how to get the inside out. Day three was more of the same. Day four we did a little extra work to try and keep the bumper zipped up but came home to find the zipper pull for the pillow laying on the floor. I'm just happy he did not swallow it. As far as a product goes We love it and the dog loves it. We often move it around the house so he sleeps or at least lays down and chews toys in the same room we are in. I guess I would like to see the next revision have better zipper protectors or a zipper sleeve that the metal piece can be tucked in to. Now I need to figure out how to order a new pillow so the bed can go back to being fully operational.
