Great chew
My pup’s favorite, great quality and it doesn’t give him a tummy ache. Lasts a good while and keeps him occupied.

Awesome!
**update: we have had this toy for over a year! I have found one other con. Once chewed if you step on it you will immediately drop to the floor in agonizing all encompassing pain or (my personal favorite) say every dirty curse word you have ever heard while clutching your destroyed instep. BUT even though this chewed bone is the demon child of a LEGO and a race car to step on my dogs still love it, still chew it and we haven’t had to replace it yet!
I have an insane chewer where toys usually last us less than 24 hours. It has become almost impossible for us to keep up with toys because of how expensive it has become. This toy is not only insanely durable but she has not left it alone for the 3 days we’ve had it.
I was concerned that being “chicken flavored” would mean stinky or sticky and I was very pleasantly surprised that it was neither! It doesn’t leave a stain once chewed, it doesn’t smell, and it doesn’t have a weird coating on it.
The only con so far is that due to it being so durable and hard it makes a loud noise when dropped on the tile or hardwood which made her nervous toward it at first but now that she’s started working on it she could care less about the noise. Super happy with this purchase and will 100% buy more in various sizes for our other pups.

Quieter than most toys and my dog loves them
Color: Football, Size: One-Size
These footballs have saved my life. I think I’ve bought close to 10 at this point? And toys primarily living outside in Texas heat is the only reason I’ve had to buy so many. In general, they are pretty durable but will get cracked if you leave them in the sun.
I have a German Shepherd who absolutely loves playing in the backyard but also takes his responsibilities as a guard dog very seriously so he barks a LOT while he is out there and unfortunately we live in the suburbs so I’m constantly bringing him inside that way he isn’t bothering the neighbors.
That is, until I got this football. The grunts are pretty quiet which is a win in my book because my dog communicates by way of squeak toy. You might think I’m joking but if I have guests over and we are having a conversation, he comes in the room and squeaks his toys violently to participate in the discussion.
For that reason, it takes me an hour to pick out a new toy at the store because I stand in the aisle squeaking every single once until I find one I think I can handle listening to 24/7. If you’re reading this review, you probably know that at a certain point, the squeaks can become unbearable. If that’s why you’re looking at this toy, you don’t have to read any further. Just buy it, you won’t regret it. That is reason enough for me to rate this 5 stars.
But the story doesn’t end there. What I did not foresee was him also using this wonderful grunting football to communicate with the neighbors. Now instead of barking outside, he grabs one of these footballs and squeaks it for all he’s worth while bucking around in circles like a bull. He still does it after having broken the noise maker in the toys. He just loves them so much.
Can I guarantee your dog will also take to squeaking this toy over barking? No. I didn’t do anything special to get him to do that, and I doubt I could train another dog to do so. Regardless, this toy has single handedly solved a lot of my dogs endearing but somewhat annoying habits in ways I could not have anticipated so maybe it’ll work for you too.

My dog's FAVORITE!
Color: Bunny (Red), Size: One-Size, Color: Bunny (Red), Size: One-Size
She goes through so many toys because she basically destroys them. This one the squeaker part broke after maybe a day or two but that's okay because she absolutely love this toy so much she wouldn't go anywhere without it. Even brought it with her on her walks which was completely a new thing. I hadn't seen her do that. She did not want to let it go. And she wanted to show it off to everyone. And when she gets upset when she is hanging out on the deck she will grab it to ease her anxiety. She also grabs it when she wants to show it off to other dogs. And she definitely wants to play tug of war with it as well which isn't a good idea. If you play tug of war it's going to come apart pretty easily. Other than that I would say it took about 3 weeks for it to rip apart. I'm on the fourth one in about 6 months. She still has the ones that are split in half.
But anytime I bring back a new one she gets so unbelievably excited and carries it with her everywhere again
