The perfect toothpaste gel for dog dental care. - Brand: CLEAN WAN - Purpose: Dental care - Product type: Toothpaste gel - Target animals: Dogs, cats - Size: 15g Thank you for viewing. This is a product I regularly purchase, but since I give it as a small treat, it's not being used up quickly, and I have a surplus, so I'm putting it up for sale. It seems the guideline is to use one tube in 15 days, or two tubes per month. * Personally, I use about one tube per month.
