Are any breeds related to a pug?

While the exact lineage of the Pug is a bit unclear, it is generally believed to be related to the Molossus breed, an ancient Roman fighting dog.

Here are some breeds considered to be related to the Pug, either through ancestry or similar characteristics:

* French Bulldog: Both breeds are brachycephalic (flat-faced) and share a history of being companion dogs in Europe.

* English Bulldog: Though larger than Pugs, English Bulldogs share the same brachycephalic features and were likely bred from similar ancient stock.

* Brussels Griffon: These small, sturdy dogs share similar facial features with the Pug, and both breeds have historically been popular companions.

* Carlin: Though less common than the Pug, the Carlin is another brachycephalic breed with a history of being a companion dog.

Important Note: While these breeds share some common ancestry and traits, it's essential to remember that each breed has its unique characteristics and needs.
