My dog loves this stuff! Literally he begs me to brush his teeth several times a day. My old dog was like that with this stuff as well and neither have had any issues with their teeth and their breath smells good. Highly recommend trying if you have an dog who doesn’t like taking care of their teeth. I use my finger rather than a brush just because that makes them not sure what to do with their mouth and it’s hard for me to get anything actually done. But with my finger I’m able to massage their gums and it really helps prevent against gingivitis and bad breath!
