My dog loves the mental challenge
My AmStaff loves this toy. It took a bit for her to figure out how to get the balls off the Velcro plate. When she finally did, she actively played with the balls for a long time. Usually, the life expectancy of a tennis ball is less than 5 minutes, because she scalps them. Not these! It seems that she values this toy more because it took her a while to figure it out. Huge winner!
