Very strong smell!
Size: Medium Chew Stick, Style: Peanut Butter
Comes with extremely strong rubber smell and I am assuming taste. My dog would hardly even sniff it let alone chew on it. I even soaked it in water and baking soda for an hour and still very strong. Disappointed would not recommend. I will not be getting a scented chew again.

Top notch customer service!
Size: Medium Chew Stick, Style: Peanut Butter
My dog is a bit too much of an aggressive chewer for this particular toy. I reached out to playology regarding this and they are sending me a toy that’s better for her!

Not very strong
Size: Medium Chew Stick, Style: Peanut Butter
We have a different bone from this company that my dogs love and it’s been indestructible for my hard chewers, but NOT this one. Within 20min of chewing he was pulling pieces off. It’s not nearly as tough as the other one we have. Pretty disappointed.
