I have special dog toothpaste and a toothbrush and the finger kind. I wanted to know if any of you brushed your dogs teeth and how often? I try to brush Abby's teeth atleast once a day because I noticed some yellow starting to stain her larger canine teeth. Should I be brushing more and does it really make a difference? It is a task to brush her teeth, I have to hold her still and hold her muzzle so she doesn't bite the toothbrush while i'm burshing her teeth.
