Don’t buy
Size: 5 in
I bought one at a store for my Rottweiler puppy, about 2 months ago, I bought one from here n about 5 minutes she had chewed the end off, they did send me another, no charge, well I received the other bone yesterday, she chewed a big split in it. Won’t buy anymore, I’m out the money, which isn’t much. Made in China also, no more. Going back to Kong toys, they do last with aggressive chewers. Don’t know why but the one I bought at the store is holding up real good.

Eh...
Size: 5 in
I had high hopes for these cause we have other spot brand toys that have last a long time. Unfortunately these just don't hold up to the test! My dogs had them broken in about 5 - 10 mins. They did smell good tho and my dogs went crazy over them before I ever got them out of the bag. Lol.

Smells too strong
Size: 5 in
My dog hates the way this thing smells. She tries to play with it, but the scent is too strong for her nose. I know it's the scent because she usually sniffs it two or three times in between trying to grab it with her mouth. She treats it like an explosive in her mouth and quickly moves away after spitting it out. She used to have a bone that looked similar to this (same material) that was unscented and she gnawed the hell out of it. My sister's pitbull spent the night and chewed that toy into bits, leaving my Yorkie mourning the loss of her once treasured bone. Please make an UNSCENTED version of this toy!!!!
