There are plenty of factors determining a breed’s popularity relative to others. However, the only statistic that actually measures breed popularity is the number of dog registrations per breed. So this tells us what is popular without explaining why it’s popular.
A review site, JenReviews.com, has published a free guide to the fifty most popular breeds in the world. For each breed, you'll find the dog group it belongs to (herding group, sporting group, toy group, etc.), temperament, training, key facts about the breed, and celebrities who own dogs in that breed.
This handy guide will give you a quick overview of dog breed characteristics. You can find it here: https://www.jenreviews.com/dog-breeds/
