Marmaduke

Marmaduke sits at the table, waiting eagerly as Dottie sticks some dog-biscuits into a bowl of ice-cream. Phil looks on in horror, spoon poised halfway between his own bowl of ice-cream and his mouth.
"Now you're really spoiling him." he says.
In fact, it's a pretty bad idea to feed ice-cream to fully grown dogs as they are, like most adult mammals, lactose intolerant.
