Before choosing a specific breed of dog to bring into your home let's go over a few things to help you make that important decision. Recognized breeds are put into groups according to the job they were originally bred for. These groups are Sporting Dogs, Hounds, Working Dogs, Terriers, Toys, Herding and Non-sporting Dogs. Among the different groups you will find a variety of size and breeds to choose from. Some breeds must be kept busy mentally as well as physically active. Others were developed as companion animals. Most breeds fall somewhere in between these extremes.
The size of the dog will vary breed to breed of the dog and life span rates from 6 yrs. to 16 yrs. with proper care depending on the breed. Choose a dog that matches your housing. Large active dogs are not suited for apartment living. Outside dogs need appropriate sized fenced yard, weather protected shelter with access to fresh water and food. Tying a dog should only be used as a temporary arrangement and a tied dog should never be left unattended.
Things to consider are having location and space for the breed of dog, spaying or neutering the dog, committing the time necessary for giving the dog exercise and play time, researching the breed and becoming knowledgeable in the breed and knowing what is involved in it's care , know that a dog takes a lot of time and money for veterinary care and keeping vaccinations up to date and last but not least be a responsible pet owner. If you can provide all these things then getting a dog may be the right choice for you.
If getting a purebred breed of dog is not for you then check out your local Animal Shelter. You can always find a variety of adult dogs and puppies available. Shelters usually put their dogs through temperament testing, food aggression testing, and testing to see how they react with other dogs and cats. They usually match a family to the right pet for them. You can interact with several dogs and make a final choice on the one that is right for you.
Some supplies needed for the dog consist of proper fitting collar, leashes for walking, play toys, nutritious dog food, treats, water and food bowls. A Kennel Crate sized for the dog is a great thing to have. It can provide a training source for housebreaking and keeping the pet bound when needed. It also provides the dog a place to go for a nap when the door is kept open. Placed in a vehicle it is a safe way to transport a dog to the Vet or for short trips.
I hope this information is helpful to you in making the choice on getting a Dog.
