About This Quiz

Who doesn't love dogs? From big-eyed puppies with their squishy tummies and all that extra fur they haven't grown into and their soft little paws, to lumbering old dogs with their salt-and-pepper muzzle hair and their rheumy eyes and their tragically hilarious gait, to the healthy bounders in between, dogs are just marvelous. They devote their sadly all-too-short lives to loving us, protecting us, entertaining us, reassuring us and covering absolutely everything we own with hair.

In return, the least we can do is make sure that we really know what we're talking about when it comes to our canine companions. Obviously the most important thing is to know how to care for your dog on a day-to-day basis, from food to grooming to discipline to exercise. It's very important for the health and happiness of a dog that its owner takes the trouble to truly understand what makes their dog tick, to set good boundaries, and to know how to spot red flags that indicate that something is wrong.

However, it's also useful to know about dogs generally: how they became man's best friend, how their bodies work, perhaps something about their history. That way we can truly say we've taken the time to get to know our very best friend. Let's see how well you know yours!
