I have a 26 year old that has very few teeth. I actually don't have to wet his grain. I feed him the Triple Crown senior which is a sole source feed. I give him the alfalfa cubes in a seperate feed dish, those I wet down. Although if I don't wet them, he'll dunk them in his dish on his own, the problem with that is his water gets pretty icky. He does really well eating though. He still tries to eat his hay but all he does with that is chew it into a cud and spit it out. I do give him a very small amount of hay because he enjoys chewing it but he gets no nutritional value out of it.

Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
