Using the oral hygiene rinse is very easy. I just dip a q-tip into the rinse and then swab it over the front part of their teeth. With dogs you use the special tip that comes with it and you have to squirt it in their mouth so this would be much more difficult and messy. My vet had already shown me how to do it and it's really very easy. The hardest part tonight was trying to catch Ziggy.
