Works great in tandem with raw carrots!

My dad's dog Dusty had really bad teeth which equals horrid breath.

While this product doesn't magically cure all, when used with feeding raw carrots Dusty's breath improved dramatically.

Ideally raw carrots in my experience usually prevent the issue, some dogs won't eat them (rare, but it happens).

This product certainly helps.

Didn't make a difference

Bought this hoping it would help with my Boston's stinky breath. Been trying it for a few weeks now and I can honestly say it hasn't made a difference whatsoever. At $3.99 CDN on sale at Ren's it was worth a try for a good size bottle, you don't have to use much of it, so it should last awhile. I will continue to use it however it says you should notice a difference in a week but that hasn't happened.
