Dogs are broadly classified into four varieties. There is a type of breed called Hounding Dogs, which were formerly used for hunting. Another type of breed is career or task oriented. These types of dogs are used for surveillance and rescue. There is a specific breed that has a highly developed sense of smell, and the police department uses these types for investigative purposes. Some dogs can also be kept at home and are commonly raised as pets.

The sale of puppies and dogs is common in all parts of the world because dogs are considered to be very loyal friends of humans. Dog breeders often purchase and adopt them, and more information is available online or at pet stores about breeders. The main thing to keep in mind before buying a pet from a pet store is that it must be a purebred and must be properly vaccinated. Important vaccinations to be given to pets are rabies and canine distemper.

One of the popular breeds is the German Shepherd and it is mostly found with all breeders. This dog looks very agile and is very intelligent and depends mainly on his masters. They are strong, curious and very obedient. They are specially trained for herding and security purposes. The normal shade is black, silver or cream. If you are looking for a great pet and a purebred, it is important to get the purebred from a respected breeder.

Another common type of dog to choose is the Pomeranian. These are fluffy and small and are very commonly found in houses. The hue is pure white with a deep black nose; sometime brown shades are also available. Great care must be taken as these dogs are covered in hair and need frequent and proper brushing. They are very adorable, affectionate and intelligent and love to be in the company of many people. They are good companions for children at home as they are very curious and show a great desire to learn new activities.

A very small and all-time favorite dog is the Chihuahua. Colors can range from sand, fawn, chestnut, steel blue, and silver, and they make an excellent companion dog to keep around the house. They are very small but more robust, very adorable and intelligent. The Chihuahua is lively and bold. All pet lovers should take good care of dogs even after purchase.
