Some dogs will probably love this.
Flavor Name: Peanut Butter, Size: Medium
My dogs were not very excited about this bone. I don’t think they are particularly picky, so I’m not sure why.

Depending on dog size, you may want to adjust bone size
Flavor Name: Peanut Butter, Size: Medium
This bone is attractive to both my 60 lb dogs. They're more light to moderate chewers at best but I remember when my youngest was a puppy, these things would buy me quite a few hours of quiet time. We repeatedly bought the ring style- must have had at least 5 as she was a rather voracious chewer.
However, I don't mind replacing Nylabones one bit; they hold up well/can take A LOT of wear and make an excellent redirect for your bored puppy who ruined your favorite pair of shoes.
I went down a size and bought a medium; I find that both dogs (full sized male Australian Shepherd + female lab/doberman mix) have trouble carrying a large size due to weight and this one is perfect for them! I would previously buy large ones who would barely ever get touched. However, you also don't want to buy one that's too small, so it's a fine line when you've got a dog who is somewhat in a weight range borderline.

Safe chew bone for strong chewers.
Flavor Name: Bacon, Size: Medium
This bone is exactly as advertised. I feel comfortable knowing it won’t splinter and last a good while. Only bone I let my dog chew.
