I have a Great Pyrenees. He doesn't mind getting brushed but after about 10 minutes he gets bored and wants to lay down. I got this and it has been a lifesaver. I put peanut butter on it and it keeps him occupied at least 20 minutes so I can do a full brushing. He loves this thing. The quality of the mat is great. They are very durable and hold up in the dishwasher. The suction is great everywhere except my wall. It's probably my wall that's the problem. It sticks to my sink, fridge, and the floor just fine. It is a truly great product. They are much bigger than I expected too. My only complaint is cleaning it. Sometimes it's hard to get all the peanut butter out of the little corners of the squares. That sometimes takes longer than brushing my dog. But overall, I am super happy with these. Highly recommend!
