This is a good chew toy

This is a good chew toy.  No, it's not indestructible.  I don't know of many chew toys that are and are safe for dogs and their teeth. This is made of good strong stuff that has entertained my dog for 3 months now. She is a 27 pound pit mix and loves this bone.  She is finally able to nibble off little bits of rubber.  Not big chunks that could harm her.  I plan on buying another. It's not expensive, it's gentle on her teeth, and has lasted for months. My husband, who is a Veterinarian, and me, who is a Licensed Veterinary Technician, recommend this toy. That said: NOT all toys are appropriate for ALL dogs. You are the judge if this will withstand your chewer.

The dogs like it, not as much as other toys but it gets played with. It has held up well

My Labradoodle love this toy. It's large enough to he can't swallow it and he hasn't destroy any part of it yet.  Seems to be made well.

** UPDATE - 5/2012 **
My doddle destroyed the ball via light chewing.

I foster dogs.  The younger ones really love chewing on this toy.  I think the nubs feel good on their gums.  We give it two paws up!

It's a good toy for playing tug-of-war and for squeaking. The toy is very durable, despite our dog's attempts to chew it to pieces.

I have purchase two of these. I have a chewer, he will tear up most items that are meant to NOT be chewed up. He chews through toys! This ball is hard enough and large enough that it takes him a while to chew it up. The first thing that he chews on is the squeaker.

I have a 55lb  pit/lab and we like this toy.  It's good for interactive play just like it says.  When she catches it on the fly she gets all gassed up.  I trim and flame the fray off the ends when chewed.  It's 4 days after Christmas and this has lasted longer than everything but the nylabones.

The dogs are tough on toys, and most of them do not last longer than a few minutes, but this toy is fun even after the tennis ball has been striped and shredded. The mutts chew and chew and chew, but their sharp-dagger teeth have not damaged the claw. Purchased a second one in case it ever needs to be replaced.

This is a fun toy for your dog to try out. They may need a little help figuring it out because sometimes they will try to destroy it to get the cookie. Is not that durable so I would be careful about buying it for dogs that like to be rough with their toys or when finding food.

I have a expert chewer, 7 month old 54 lbs, Lab/pit/? mix who destroys EVERYTHING. He really seems to like this bone. We bought the beef version and it seems like he likes the shape. He was able to make some teeth marks in the bone after one day of chewing but it still seems that it will last him a good while before it hit the toy graveyard.

These bones were readily received by my dogs. They chew them for at least an hour a day. It's good for their teeth, and it seems to calm them to have an interesting activity. A nice addition to any dog's toy box. The only issue I have with these is that when I ordered a set of four Amazon sent me only three and charged me for four.

I have a 7 week old lab puppy and he loves this chew toy! He's had it for a week now and so far it's held up well with his sharp little puppy teeth.

This is one of the few toys that my dog hasn't been able to chew up, and loves to play with it.

This is a great toy for dogs who love treats and/or are motivated by food.

I bought this item tentatively because I have a year-old German Shepherd who loves to chew! This, however, has become one of my dog's favorite toys; she's had it for a year now, and has managed to chew off the white "strings", but the rest of the football is intact and in good shape. I recommend for a larger dog, as it could be harder for a smaller dog to hold in its mouth.

I saw my puppy with this toy having a lotta fun chewing on this.  She really likes it.

My small dog loves playing with this toy. It's one she can chew to her Heart's content without damaging it. And perhaps because it is small, my big dogs mostly leave it alone
