No. 5: Beagle
In the AKC's Top 10 list every year, this breed comes in two sizes, 13-inch and 15-inch, and is known for its bray rather than its bark. Beagles can be mischievous, but make great family pets. They have been beloved for years, as demonstrated by the enduring popularity of Snoopy, Charlie Brown's best friend in the Peanuts comic strip.
