Is giving alcohol to dogs illegal?

Not that I do, but say someone 21 or over gave their dog alcohol and the dog enjoyed it. Does it count as abuse? Even if the dog liked it? I don't think there is a law, but do you think it should be a law? Or do you think it's just silly to even think about making that a law?
