Dogs loved
The dogs couldn’t wait to get their choppers on this one. Great for cleaning their teeth even reaching in the back no odor

Too big for small dogs. Very misleading claim
This is NOT for small dogs! My 13 lb Morkie couldn’t get her mouth around it and I gave it to my daughter’s dog who is more like 20 lbs.
I need a chew toy like this to put dental paste in that she can use to clean her teeth while she chews. I have an old one it but it’s getting worn. I wish I could find a replacement.

Well done
Amazing. Not that my dog chews it but it can be used as a bully/colligen/yak chew holder. & it is softer when it hits the floor. Well made. Not exactly as it was intended or advertised but excellent.
