Sealyham Terrier versus Spanish Mastiff: Overview

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

Furthermore, the Sealyham Terrier belongs to the Terrier Dogs group. Terrier Dogs were originally bred to go underground to hunt rodents and other small wild animals (vermin). Terriers come in a wide range of sizes and shapes, but all terriers are energetic, highly intelligent, and territorial. Terries also have the tendency to escape. They require a securely fenced yard.

On the other hand, the Spanish Mastiff belongs to the Working Dogs group. 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.
