Brushing Coat and Teeth

Hi,

I have a 19 mo. old rough coat JRT that absolutely HATES to have his coat and teeth brushed. I've tried everything(he's long gotten wise to the peanut butter on the wall trick, unfortunately!)! First of all, do I have the right brush for his coat? I'm using one of those ergonomically correct slickers. I don't think the brush bothers him so much as having to sit still in one place!ha ha And caring for his teeth....well, I'D rather have a root canal! He can be a little monster! He either thinks we're going to play "tug" with the toothbrush, or he'll gulp all the toothpaste off and spit it out! He just had a mild teeth cleaning at the vet, and fortunately he doesn't get a lot of buildup on his teeth. I feed him dry kibble and he loves giving his marrow/soup bones a workout, so he's doing a lot of cleaning naturally. But I do want to do my part to keep his teeth/gums as nice and clean and white as they are now! How often should I be brushing his teeth, and does anyone have any great ideas for making both brushings(coat and teeth) more enjoyable for the dog(and me!)?

Thanks for all the wonderful advice, as always!
