Seriously durable
I have 3 XXL dogs (how convenient this comes in a three pack!). They will destroy many toys marked for aggressive chewers, but not these. Plus, they are good sized, leaving room for me to hold them while they are chewing when I elect to do that.
I don't really smell anything in the toy itself. Maybe the dogs do, but not enough to keep their interest more than a few minutes. However, when I smeared it with peanut butter, it was a whole new story. All 3 of them LOVED that and spent some time getting every last morsel of peanut butter out of the toy. In the meantime, because of the honeycomb texture, I feel they were getting a decent dose of tooth cleaning as well.
I wish the texture were a little deeper to fit more peanut butter, but I suppose it is probable that would make the surface texture less durable.
My dogs like them, so I do too!

Best chew toy for a small dog
My Pomchi puppy was chewing on anything and everything, including me. He had a million other toys that he just didn’t care about. This is small and perfect for his tiny, ferocious mouth. It seems very durable so far and believe me, he doesn’t go easy on this thing. It’s hard enough that I can tell it feels good on his tiny, razor sharp teeth. The bone keeps him busy all throughout the day, and it doesn’t squeak, which is good because squeaky toys freak him out. I highly recommend this if you have a tiny, teething monster.

My puppies favorite bone to chew
I’ve bought at least a half a dozen of puppy bones for my doggie to try, the majority being from Nylabone, and the others from hartz. Her first bone was a pink puppy Nylabone xsmall sise. She definitely must have liked that one but unfortunately I felt like I had to take it away from her too soon, she was teething more then, but even so, thought it was unsafe when I saw little pieces come off and her trying to chew them.
I really like these the best, though I don’t think I’ll be ordering any more at least not until she finishes her new ones. I don’t know what flavor she likes more, it might even be a color thing, but I think she prefers the orange ones which are peanut butter flavored. These are really ideal for toy breeds. My pup is still growing, she’s almost 7 months now, but unsure when she will stop growing, for reference she is a chocolate sable yorkiepoo, not sure of how much she weighs right now, but would estimate she weighs around 5.5-6 pounds. These are perfect for her, and I feel like they out live the other ones I’ve gotten, or she just has more interest in them. I bought a second package on subscribe and save (or possibly on my first and forgot I had a new order and didn’t return), but didn’t open the new package until recently as I felt the first pack were starting to look a bit knawed off, but in the middle there was still plenty of chew left. Oddly, she has prefered the old orange one vs the brand new orange one despite them being the exact same toy and flavor. I think she just hasn’t broken it in yet and I overloaded her with too many toys! I also got them for a great price, for some reason I noticed that the price increased nearly double of what I paid, and now they habe decreased a bit but still are about $2 more than what I paid. She loves all toys, and has many plush kinds. She still teeths, so when she is extra hyper and such, I feel like the bone helps occupy her for a moment. All in all I’d reccomend these out of any puppy bones to chew for toy breeds!
