Dogs love them
Color: GT-2P
I have 5 large dogs and they love their chew toys but are picky and tend to tear up the ones they like. These large bones are perfect for my 70 - 90 pounds dogs and are almost indestructible. Most chew toys last a day with them these have lasted a couple of weeks and show no sign of being destroyed anytime soon.

Works for my aggressive chewer
Color: GT-2P
It is extremely hard material! My puppy is 6 month old and rips through everything and these absolutely have lasted longer than any plush toys, bully sticks etc. I honestly didn't think I would like them for her but she definitely aggressively choose on these all the time and they hold up so well. If you have a dog that aggressively choose these work for mine.

My Belgium loved her new toys…. Instantly started to destroy them … I can already tell these will last a while with how tough they are.

Got for larger pup, but younger/smaller pup likes them more.
Color: GT-2P, Color: GT-2P
I got these to try for our older pup that likes to chew on sticks and is always wanting to bring one inside, but I think he just prefers sticks instead. Our younger pup loves them though and steals them...runs off with one and chews on it...comes back and steals the other to take to her pile of toys for eventual destruction. That's just her nature. Ha ha! She is about 35 lbs. and, though these might be a little larger than I might have initially gotten for her, they are great and work just fine to keep her busy and entertained.
I think the value for 2 super tough chew toys that are going to last more than a week is great. The texture of them is good for gnawing, or at least she thinks so. I would get them again but will not need to for awhile.
