Jester LOVES anything alcoholic. He would literally knock the beer out of my Dad's hand if he stood clos enough. He would suck it down too if you let him. Of course we never let him, but occasionally would let him lick a little bit out of our hands. (Pour it into our hands and he would lick our hands). I haven't noticed it effecting him at all, but I wouldn't give any more than that handful, Especially when treats are less expensive than beer.
