I love dogs and I have three of them. 
Dogs are great. They are a member of the "Canis" genus and are the most abundant terrestrial carnivore.
One of my dogs is a livestock guard dog, he is super smart and keeps the cattle and goats safe
Your dog is one that performs a role for people. Other uses are assisting police, hunting, and aiding handicapped individuals.
That is right but the other two are just spoiled pets that love being pampered lol
They are busy being "man's best friend". We sure love our furry companions.
