Our All-Time Favorite Chew Toy
My Dog's FAVORITE chew toy. It lasts so long. I love the bright color and the durable silicone. She can chew this thing forever without breaking pieces off of it. I finally bought her a new one because I felt like she had the other one longer than is probably sanitary, not because it was unchewable or damaged. Please don't ever stop making these Nerf Dog Bones.

No Peanut Butter Scent
As mentioned in about her Nerf toy review, these are pretty much the only toys we buy for our power chewer. And our boy LOVES peanut butter— pretty sure he’d jump off a cliff for a spoonful of Jif. So when I saw 1) our brand of toy, 2) in peanut butter scent, it seemed like a no-brainer. I thought he’d smell the peanut butter and tear the package open before I even got home. Much to our dismay, this one had absolutely no smell and must not taste like peanut butter either, because he has very little interest in it.

Lacks durability
Lacked durability. Clear silicone outer shell started to break off once my dog chewed it. Lasted only a day or two. Wouldn’t recommend.

Wonderful, safe chew toy
Durable but safe for dogs teeth. Our large red puppy chew on this all the time and we’ve had it for weeks.
