Some dogs will patiently put up with little children who pull their ears or accidentally poke them in the eyes, while others will not and map nip or bite back in defense. So if you want a dog who is excellent with children avoid breeds which may have a dominance streak or that have short tempers.
So keep in mind that if you choose a breed with a long coat you will either need to get it clipped regularly if you want to avoid brushing it so much, or if you choose to keep it long or even medium length you will have to brush it every day.
Today some of these jobs are performed in other ways and dogs don’t do the work they used to do. Hunting is a sport today and most of us don’t have to hunt with dogs to put food on the table. English Cocker Spaniels and Irish Setters are more popular as family pets than as hunting dogs. Dogs aren’t commonly used to kill rats today and it’s been a long time since the adorable Yorkshire Terrier, originally bred to kill vermin in textile mills, was used for this kind of work. Dogs still have some specialized uses for search and rescue, narcotics detection and other kinds of detection, along with other specialized skills such as therapy dog work, but most people don’t need to use dogs for work. Nevertheless, breeds still have their admirers. Some people love a dog’s appearance. Some people love a breed because they are from the same tiny corner of the world and they feel a kinship with the dogs of their ancestors. Some people love the temperament of a certain breed or its athletic ability. There are all kinds of reasons why people love a particular breed.
Dogs have been selectively bred for thousands of years, sometimes by inbreeding dogs from the same ancestral lines, sometimes by mixing dogs from very different lines. The process continues today, resulting in a widening in appearance without speciation, "from the Chihuahua to the Great Dane."
