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!

Nice chew toy
Puppy likes but for me to hold so she can chew is a little difficult.

Love nylabones
Nylabbones did it again. The pugs love these. They're so cute and tiny. Perfect for their lithe selves. They're still safe and soft and very chewable.

Not safe, easily chewed bits off
Mixed feelings. My puppies love them and love to chew on them but also chewed the edges off pretty quickly. I had to take away the first one after only a couple days of intermittent chew so it’s really not durable or long lasting. I don’t feel this is safe for a 12 week old puppy which is super small and can be a choking hazard.

Very Small
These are tiny! Just perfect for my little dogs but one was lost within the first few minutes so I had to order another. I'm not so sure how safe it is for the fur children to chew on non-edible, non-digestible plastics but they seem to really like them.
