Such a fun novelty item but so cute and the pups love them!
Size: 7"
My grand dogs loved them so much I had to actually buy a set for our house and their mom's house! :) Perfect size for our pug and chug. Fits in their mouth perfectly and funny enough they always have the right end in their mouth. The other day our pug went to sleep with it in her mouth for an hour!

Not great
Size: 7"
Thread is already coming out. The last one she had lasted 2 years. (Was not bought on here) The only reason for ordering her a new one was because we left her old a hotel.

Not durable, but cute!
Size: 10"
It was destroyed in minutes. Not for heavy chewers. Was funny for those few minutes it survived. Basically lasted as long as a cigar would 🤣
