A good greyhound owner brushes his dog's teeth every day or two. So far, that's like asking me to defuse a bomb every day or two. It's a tad unnerving to invade the mouth of a hound who doesn't know you very well yet. Those teeth look real big up close.
So I'm nervous. Jackson knows that, and it makes him skittish. But we're making progress. For a couple of days, I did nothing more than hold his snout for a few seconds. Yesterday, I reached into his mouth and rubbed his teeth and gums. That got him a treat. Then I used a washcloth with some toothpaste on it to do a little brushing, followed by another treat. It's coming together.
(The greyhound folks gave us a toothpaste/toothbrush kit. The toothpaste is tasty, and no rinsing required. The brush has a long handle, so that you can get all the way up in the snout. But many people suggest using a cloth or gauze pad instead of the brush.)
