Query: Not recommended for chewers

I purchased this product almost six months ago and have given it time to write this review. As pet owners, we are always looking for a product that entertains and keeps our four-legged friends busy. Especially after a long days work, etc. I have a 38lb. black Spanador (Cocker Spaniel and Lab mix). This breed is high energy and needs to be active much of the time. She is also a CHEWER! I do not recommend this ball for really any dog. No matter if the dog is high or low energy or chews/not chews. In my experience the ball made her more 'spastic' and crazy. I believe it was overstimulating her in a negative way. Also, the ball started to break apart in little pieces after only a few hours. I do not recommend this product. Maybe if the manufacture rubberized it in the tough material that Kongs and other durable products are made out of. I found that walks and fetch still prove to be her favorite past times. They just want to be with us.
