When I went to the vet, he told me that I had to start brushing Pennys’ teeth. She was builing alot of plaque and she already lost 5 teeth last year. I do not want her to lose anymore, or to go through that again. I’m not crazy about dentists my self. The toothpaste was pretty pricey – $10.00. It is chicken flavored Enzymatic Toothpaste by Virbac. It also comes in beef flavor – next time.
