With approximately 78.2 million pet dogs in the United States it's clear that Americans are big fans of their canine companions, and advertisers have taken notice. Today, dogs are helping advertisers market not just pet toys and dog food, but also cars, beer and even the lottery.

Take a look at some our favorite commercials starring man's best friend.
