durable. interesting shape
Size: 9.5 inch
I like that chew bones come in a variety of shapes. This shape is currently not my dog's favorite but that is ok. She plays with it a bit. It is durable and she will get around to it sometimes.

My dog loves bam-bones
Size: 5.25 inch (Pack of 1)
I wasn’t sure how my dog would like this since it’s stick shaped instead of the typical Y or T shaped bones. She was apprehensive at first but eventually loved it. She’s on her second one now. They don’t last quite as long as the name-brand nylon bones but she loves them the same and they’re a better price.

Good product, except that dogs don’t seem interested.
Size: 5.25 inch (Pack of 1), Size: 5.25 inch (Pack of 1)
It’s a good side for 8-20lb dogs which are the size dogs I foster. So far none of my fosters have been interested in this particular toy. I’m not sure why. It seems like a quality product, that is not so hard that it will hurt teeth but, durable enough that it will last for moderate chewers. I appreciate that it had some texture for pups to work their paws and mouths around.
Again, none of the dogs here have been interested yet but other than that, as far as I can tell the product is good. I’ll update if I ever get a foster that goes HAM for it.

Ok
Size: 5.25 inch (Pack of 1)
My pups not overly interested in it. If it had some texture it would be better. The price was right though, and it gives him some variety in his toys.
