start now!! I started brushing Lola's when she was a puppy with dog toothpaste. They even come with a small head toothbrush. She is now totally used to it. She doesn't like it but lets me brush and even let's me open her mouth wide to get the back ones and she is now 2 yrs. old.
I don't do it everyday but do make sure to do it at least 2 or 3 times a week.
Her teeth look great--no tartar |
