Neapolitan Mastiff versus Sealyham Terrier: Overview
A very important difference between the Neapolitan Mastiff and the Sealyham Terrier is the size difference between the two dog breeds. The Neapolitan Mastiff is a giant-sized dog while the Sealyham Terrier is a small-sized dog.
Furthermore, the Neapolitan 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.
On the other hand, 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.
Neapolitan Mastiff versus Sealyham Terrier: Comparison Table
The table below compares the Neapolitan Mastiff to the Sealyham Terrier based on different important factors such as Price, Health, Kid-friendliness, etc.
When a dog breed scores higher for a factor than the other dog breed, the box of the breed that scores higher is shaded green and the box of the breed that scores lower is shaded red. When there is no difference between the breeds for a particular factor then the box is shaded gray for both pets. Also, when the factor is not important in picking a pet, or when the factor cannot be compared between two pets, the box for the factor is shaded gray for both pets

However, some factors such as “Price”, “Average Lifespan”, etc. cannot be on a scale of 1 to 5, so they are not on a scale of 1 to 5 in the comparison table.

Health Problems of Neapolitan Mastiff versus Health Problems of Sealyham Terrier
Every dog breed has its own set of health problems that it has a tendency to develop. There is nothing like a perfect dog breed.
Both the Neapolitan Mastiff and the Sealyham Terrier are prone to certain genetic health conditions. The Orthopedic Foundation for Animals (OFA) is the organization that keeps track of health problems in dogs. Based on the extensive records that the OFA keeps, the OFA knows what health problems each dog breed is naturally prone to develop. Hence, the OFA recommends which health screening that breeders should perform on a dog breed to make sure that the breeders won`t breed `defective` dog parents that can pass down defective genes to their puppy offspring.
The more health problems a dog breed is prone to develop, the more health tests the OFA will recommend for that dog breed.
Based on our review of OFA records, we found that the Neapolitan Mastiff is prone to more genetic health problems than the Sealyham Terrier.
This is because the OFA recommends more screening health tests for the Neapolitan Mastiff than for the Sealyham Terrier.
