Toothbrush Chew Stick

Nubs all over it – The whole surface is raised, so it works the gums wherever your dog happens to be chewing.

A groove for paste – There's a channel along one side if you want to run dog toothpaste into it.

Hollow through the middle – Push something soft in and it stops being a chew and starts being a puzzle.

Flared ends – Keeps it from going too far back in the mouth.

Colour is pot luck – Green, blue or yellow, whichever comes off the shelf.
