Perfect dog-lovers and beer enthusiasts, this hilarious birthday card is a barking good time. If each beer is equal to seven dog beers — like years — then anyone counting in dog beers should soon be slobbering like a dog, too. Don't give sappy, lame birthday cards, especially if the birthday boy or girl isn't a pup anymore. Birthdays are a time for joy, celebration and, yes, a time to have one too many beers. If you count in dog beers, then you may need its hair in the morning, though.
