We got this in our first super chewer box for our one year old pit bull terrier mix who is about 45 pounds. She LOVES this; I think it might be one of her most favorite toys. She's a squeaker seeker and she loves the harder to squeak handles (and she hasn't killed the squeakers yet - and this from a dog who usually does so in seconds) and chewing on the middle. The middle area is looking pretty worn down now after a bit over a month of obsessive chewing, but the toy is still safely in play. Impressed with the combined excitement and longevity we are getting from this toy!
