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.
You do not have to have own a large house to own a large dog (although a tiny apartment is not going to be big enough for one of the giant breeds). If you can take him outside for a good hour of two of exercise every day... a large dog can live in a small house or apartment just fine.
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.
If you do not have time to exercise your dog daily with a brisk walk and lots of running choose a breed that does not have high exercise requirements. All of the breeds who require high amounts of exercise make terrific jogging, hiking, and ridding companions. So if you want your dog to accompany you on long runs choose one of these highly active breeds built for endurance and as much exercise as you can throw at them - they will love you for it (and a tired dog is not destructive).
