Great for aggressive chewers!
This item has held up for 4 months so far! My dog loves it, carries it everywhere. It's one of his favorite toys and he's been through so so many but this is the only one to hold up. However there are CONS! We have dubbed this bone "the cheese grater". My dog loves to bring his toys to us and press them against our legs to get our attention. So after a little chewing, the ends become very rough. When he runs by us with it in his mouth or presses it up against our legs, it tears our skin up! Also, the bone is very heavy so we have to watch out for our toes because Hank will drop it right on our feet if we aren't paying attention. Other than that, it's great! When it gets dirty, I just throw it in the dish washer and rinse it off after the cycle is done. Cleans up nicely! Would buy again if needed! Recommend for aggressive chewers!

This is the one for your dog
Size: Large
My 40 pound Mini Aussi is a very agressive chewer and goes through toys lightning fast===untill I got her this bone. She has had it several weeks and it still survives. She takes it everywhere she goes and it is, by far her favorite toy. I think she has met her match. One warning though. We have hardwood floors and it gets a bit noisy at times. That's just a small issue though. If Dixie ever destroys this (doubtful) I will not hesitate to buy another. Great toy and I coming off and she coming off and she wqw cfully recommend it. WARNING{ This is/was a great toy for my 50 pound Austrilian Sheperd, However it is not indestructable. It lasted about 3 months until the white parts started coming off and she was injesting it.

Great product
Size: Large
I was hesitant about buying this product, but I'm so glad I did. My dog (who is a very aggressive chewer) absolutely loves this toy. He will spend hours chewing on this toy. He carries it around the house and will show it off to anyone who visits. Since getting this toy for him, he has stopped chewing up other toys and focuses his chewing and destructive chewing on this toy. He has not managed to destroy this toy as of a month of chewing.
