Mastiff versus Sussex Spaniel: Overview

A very important difference between the Mastiff and the Sussex Spaniel is the size difference between the two dog breeds. The Mastiff is a giant-sized dog while the Sussex Spaniel is a small-sized dog.

Working Dogs were developed to assist humans in some capacity – including pulling sleds and carts, guarding flocks, guarding homes, and protecting their families. Breeds in the Working Group are known for their imposing stature, strength, intelligence, and fearless. Because of their size and strength, working dogs require a structured home life and firm, fair, consistent training by someone who can provide leadership without resorting to anger or physical force.

On the other hand, the Sussex Spaniel belongs to the Sporting Dogs group. Sporting Dogs were bred to help hunters catch and retrieve feathered game. Some sporting dog breeds such as Retrievers, which were built for swimming, were bred to hunt waterfowl in water. Whereas sporting dog breeds like setters, spaniels, and pointing breeds were bred to hunt quail, pheasant, and other game birds nest on grasslands. Many Sporting Group breeds have thick, water-repellent coats that protect them from harsh hunting conditions.
