01 Chihuahua: The Saucy Micro-Companion
Weighing in at under six pounds, the Chihuahua is the smallest recognized dog breed in the world, but nobody has told them that. Originating in Mexico, these tiny dogs have a history that dates back to pre-Columbian times.
Today, they are famous for their intense loyalty, often bonding fiercely to a single person while remaining highly skeptical of everyone else.
Chihuahuas boast an impressive lifespan of 14 to 16 years. According to the American Kennel Club, they pack the confidence of a 50-pound dog into a 5-pound body.
You will often see them standing their ground against much larger dogs. Because they are highly alert, they make excellent watchdogs, though you must socialize them early to prevent excessive barking and suspicion of strangers.
Give your Chihuahua plenty of warm blankets, as they notoriously hate the cold. While they enjoy indoor playtime and short walks, you need to use a body harness rather than a neck collar.
Their delicate windpipes are prone to collapse, so pulling against a traditional collar can cause severe respiratory damage.
With the right positive reinforcement training, these brilliant little dogs master complex tricks and excel in obedience work.
