Vetstreet’s Ultimate Dog Breed Challenge

Let’s start small. Do you know which breed is Queen Elizabeth’s favorite? And can you detect the difference between a French Bulldog and a Boston Terrier? See for yourself with our small breed quiz.

Now, let’s try the opposite: How much do you really know about slobbery pooches like Mastiffs, Newfoundlands and Saint Bernards? Check out these and other big pals in our giant breeds quiz.

Not to be outdone are the large breeds, like the Collie, Labrador Retriever and Bloodhound, among others. In our large breed quiz, see if you can answer questions like: In which year did Lassie debut, and which breed delivered much-needed medication to an Alaskan village during an epidemic?

OK, OK. So you’ve mastered many traditional breeds. But what about newer designer dog breeds? You might be able to identify a Labradoodle, but how about a Cockapoo or a Basador? Try our designer dog breed quiz.

Finally, we’ve reached the end: our tails quiz. All kidding aside, this might be our trickiest test to beat — can you determine a dog’s breed just by looking at her tail? In this quiz, match the tail to the breed.
