The Autumn Vital Health magazine (28th Jan - 24th Feb 2013), contains a Pet article titled "Creature Comforts" (page 29).
The article contains a statement relating to pet dental care:
"Look for a specially formulated product containing xylitol - an ingredient commonly used in human dental care..."
It is imperative that only specialised pet products that contain xylitol, such as Aquadent, are used, and directions are followed. Products formulated for human use, including toothpastes, should never be used on your dog.
Please ask in store if you require any further information, or check with your Vet if unsure.
