Tough, durable, and appealing
Color: GT-2P, Color: GT-2P
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.

Received these chew toys earlier today and my dog latched onto them quickly. He has been alternating playing with these since delivery.

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.

Not indestructible, but well worth it
Color: GT-2P, Color: GT-2P
First things first…it’s solid, literally. Very hard and if you have tile or wood floors, it’s ridiculously loins when it hits the floor. With that said, we’ve had our dogs chewing on these for about a month now. All 3 are aggressive chewers. As you can see in my pic, there are signs of chewing on the ends of the bone. I’ve noticed they all seem to gravitate towards them assuming they think they can chew through it. Not the case. The material itself made of is hard but I almost think they enjoy the feeling of the bone against their teeth and gums. I regularly watch our biggest chewer lay on the couch for what seems like hours just biting on it. The bone itself has held up extremely well and haven’t shown any signs of splintering, breaking, or falling apart. This making us feel the bone is safe considering how much they love to chew and how well it’s held up. It looks like a bone. This seems to be a factor in them wanting and/or seeking it out when they want to chew on something. Great to keep close in the living room and gets almost immediate engagement from all of them when I pull it out. Well worth it if you have problem dogs that chew everything and anything. Great as a distraction and from what we’ve seen, great for hours of engagement. Highly recommend for sure.
