They can chew off the plastic
My dog loves the bone, but after a few moments, we noticed some she had already chewed off some of the bone! We upsized to avoid this issue as well! We know this is expected, however it is also concerning if you have a dog that can take off large chunks, which we don’t.

After 2 weeks update 9 month review
Updated. 9 months of aggressive chewing. Pic 2 - Purchased this 2 weeks ago. I have two Pitties. An 8 yr old 80lbs and a 2 yr old 45 lbs. Little pieces flake off as they chew. It is hard finding tough toys for very aggressive chewers. I’m not impressed by these. However, the dogs do love them.

Chew incessant dogs

Very tough, My Dashound is a Tasmanian Devil & young this has really slowed his roll, and still enjoying the chewing & licking with peanut butter. Great item!
