I can no longer get the Deerhorns they loved, so I have been buying these. They are so excited when I open a new package and give it to them. They like all sizes. They place their feet on the handles and hold it, making it easier for them to chew on them. They are a little less expensive if I visit a local Walmart store. The problem is that they are often out or not stocked.

my dog loves it, but is chewing small, jagged shreds off of it

Flavor Name: Bacon, Size: Large - 2 Pack

My dog loves this bone and he is able to easily hold it in his paws due to the shape. He is half bernedoodle and half bloodhound quite large 75 pounds and is a very aggressive chewer. My only concern is that he is biting off small pieces of what I believe is plastic since it’s the nylon one. I know he’s probably ingesting some of the pieces. Is this supposed to happen?

Excellent chew option!!!!

Flavor Name: Bacon, Size: Large - 2 Pack

My pups love these! They are able to easily hole them with their paws and they must like he taste as these are their.favorite ‘bones’. They also last along time and do not ‘splinter’. My 12 year old loves to throw it on the air and play with it!
