There is a wide range of sizes and shapes among domesticated dogs.
It is important to note that many large breeds, which are commonly referred to as "rug dogs,"
have characteristics that defy the preconceptions that are commonly held.
These dogs are able to thrive in domestic surroundings while yet retaining their distinctive qualities.
Laboratories are especially well-suited for owners who frequently have guests or who have children,
as they thrive in situations that are abundant in opportunities for social interaction.
It is possible for them to grow to be enormous, weighing up to 80 pounds.
