Dogs and children can be a perfect match.  A child's dog is a friend who's always in the mood to play; a companion who loves you even though you've been bad; a cure for being alone who will walk by your side or run by your bike mile after mile.

Perhaps no group of dogs have contributed more to idioms in the English language than the Hound Group. 
"stop hounding me" 
"he ain't nothin' but a hound dog" 
More often read in novels than heard in speech is "hangdog expression" which refers to the often sad-looking expression of hound dogs.

Non-sporting dogs is a catchall group composed of breeds that may previously have been developed for work or hunting but which have evolved into primarily companion or family pet functions.

Sporting dogs were developed to aid their masters in hunting small game.   They are some of the most beautiful of dog breeds and thrive on vigorous activity.  These intelligent animals do best with two good sessions (20-30 minutes each) of vigorous activity daily – perhaps a brisk walk in the morning and a game of fetch later in the day.  Most of them love water so swimming is an excellent exercise for them.

Named for "terra" or earth, terrier breeds were developed to eradicate vermin around homes and on farms. These dogs were trained to dig into burrows to kill small pray and to chase and kill rodents to protect grain bins. These short legged breeds were fast and efficient in controlling pests.

Canines in the Working Group are medium to extremely large sized dogs.   From performing avalanche and water rescues to protecting property, these dogs have been invaluable assets to their owners for many years.
