This double suction cup dog treat chew toy is really awesome! It works great for indoors on my wooden floors, and keeps my active furbaby very busy. I put in a few small treats and she spends a long time trying to get them out. The suction cups hold very well. The nubbys on the ball also work well for cleaning her teeth. I can play tug with her either in the house or outside, if the weather is nice. It is durable and sturdy and works well for an indoor toy. Since it is cold outside now it is a great indoor toy for her. I love it!
