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.

Recommended for Seniors, Not for Chewers
Size: Medium Chew Stick, Style: Pork Sausage
My 12lb dog loves Playology toys because of the long-lasting scent that's stimulating for her (even though I can't detect the smell). I got this toy because I wanted to add a different texture to her toy bin since most of her toys are rope & plush. Unfortunately, after only 10 minutes of playing with this toy, she managed to tear the pieces of the rubber off and I had to take it away so she doesn't choke on the pieces that were breaking off. Now I see why this toy's recommended for senior dogs. Definitely not recommended for active dogs or heavy chewers.
