(NewsUSA) - As companies downsize their workforce, Americans are also downsizing their dogs.
Labrador retrievers remain America's number-one dog, but dogs under 20 pounds are enjoying increased popularity. Yorkshire Terriers, Beagles, Boxers, Dachshunds, Bulldogs, Poodles and Shih Tzus all make the American Kennel Association's (AKC) list of top 10 dog breeds.

Small dogs can require less food, less space and less exercise than larger canine companions, making them a perfect fit for the busy homeowner who wants a lap animal to cuddle.
Of course, small dogs come with their own challenges. The great outdoors, for example, presents a greater hazard to Chihuahuas than to Great Danes. In April 2009, one 6-pound Chihuahua puppy made the news when she was reunited with her owners after being blown away by a 70-mile-per-hour wind.
Luckily, most small-pet problems prove more mundane. Small pets can squeeze through fences that would stop larger animals. Areas like pools can pose threats -- a very small pet might not be able to climb from the pool.
But as small pets become more popular, American pet care companies are creating products to keep tiny companion animals safe, such as invisible fencing. Unlike traditional fences, invisible fence systems can go through rocky terrain and wooded areas and under water. Pet owners can use the system to section off their driveways, pools or gardens or specific rooms in their home, as well the perimeter of their yard.
