Four stars just because it was advertised as accurately as it could be, but my dog didn't take to it much-- it's pretty big, and very hard, and these thing in combination make it not a super enjoyable chew toy (and then you add on all the knobs)... if my dog could get his mouth around it better maybe (lab pit cross). He plays with it some but not a ton. Also heavy and hard to squeak. All that being said, it's definitely durable!! Wouldn't want that thing hitting me in the head for sure.Have a small dog who chews through tough pitbull type toys in mins. Seems sturdy enough but it's very heavy so he's not really interested.I think the size (large to medium) is not accurate. It is m ore like large to extra large. I think they should make one a little smaller. Although my dog loves it, it is a bit hard for him to handle sometimes.My GSD mix is tough on toys and crazy for things that squeak. He was instantly enamored with this toy and it seems highly durable. He loves gnawing in the nubby texture and enjoys chasing it as it bounces crazily across the yard. It’s a heavy toy, so watch out where you throw it.It's great. He's chewed and chewed on it till it's dripping in slobbers. It's squeeking the whole time and no holes. I've discovered if it doesn't have a squeeker he will destroy it, even though it says virtually indestructible.My dog distroyed the sqeaker part in a day. Other than that, its still holding up. Not worth the price
