The Woofer (/ˈwʊfər/), also called a big ol' doggo, is a breed of domestic doggo, being larger than a doggo, and considerably larger than a pupper. Being a more generic archetype, it can fall under many different breeds of doggo, such as a Bernese Mountain Dog, German Shepherd, or St. Bernard. This type of doggo was selectively bred to be large, proving to be a very strong and effective guard doggo.
However, these doggos struggle in the ability to bamboozle, surrendering that ability to puppers and yappers. Woofers prefer to succeed in doin' enemies a frighten.
