The Smallest, Tallest, Oldest and Fastest

We all know that cats and dogs come in all shapes and sizes, but when you place a 6-inch-tall Chihuahua next to a nearly 3-foot-tall Irish Wolfhound, it becomes quite apparent just how dramatic those breed variations really are.

From the world’s oldest dog breed to the least hairy cat breed, we rounded up nine of the most extreme feline and canine breeds.

Smallest Dog Breed — Chihuahua

Chihuahuas might be the tiniest dog breed, but they don’t act like it. Don’t be surprised when this feisty little dog tries to pick a fight with a Rottweiler at the dog park. Along with her spirited and fearless personality, the Chihuahua is exceedingly loyal to her favorite human.
