I bought these for my lab who has so far shredded every tennis ball she's had in seconds, for the price I figured it was worth a try even if she did destroy them, she's now had them for months, loves taking them on walks and will spend hours chewing on them without any signs of wear, I would highly recommend these to anyone with a heavy chewer, these have survived better than her kong toy which we had to replace with the extreme version, so these really are tough.

My two year old Labradoodle is a power chewer; standard tennis balls last a few minutes. The Chuck-It balls were a specualtive purchase and I didn't really expect them to last. They are amazing!! My dog adores them, they are her Best Balls, and she regularly brings them for us to play with her either inside or outdoors. They readily re-inflate back to their normal shape which is great as she likes to chew on them; they make a pleasing (for her) squelching noise (a little off-putting if we have visitors!) and have proved indestructible (so far). I'm about to buy quite a few, so we have some "spares", and have been so impressed with them I'm going to try some other Chuck-It products.

I and my dog LOVE these! Previously she would only go for tennis balls which are a nightmare as she's really worn her teeth down. I've tried every make; Kong, The Dogs Balls, Hyperpet, Chuckit tennis balls etc. None lasted and none were soft on her teeth as claimed. It took a bit of me bouncing this one around and not letting her have it to make it prize procession, but now it's as love as tennis balls. It doesn't harm teeth, is so far indestructible and my dog is a heavy chewer, it bounces magnificently and is lightweight. Really relieved and impressed.
