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.
