Hi! Our dog is 5 1/2 years old. He has been with us since he was 10 weeks old. I brush his teeth every night since he started to have his adult teeth. Even though I brush him every night, he has some tartar, but he never develops bad breath. After only one mmonth ofusing Dog Teeth Tartar (R) as well as Dog Gum Disease (R), he has no evidence of having tartar. His teeth are white and clean! Thank you to the developers for creating these programs!!
