Dogs are among the most popular pets in the world.

   Dogs are among the most popular pets in the world. Among the many breeds of dogs, finding the particular type that suits an individual’s needs is an arduous task. Humans have historically desired certain traits in their pets and, therefore, have produced by artificial selection,  the vast variety of dog breeds (Nearly 400 different breeds). Dogs of many sizes, shapes and color, appear in archaeological and artistic records of almost all cultures, dating to thousands of years ago.  Know your habits and correlate these with the  different dog breeds to decide which breed is appropriate for you. Examine your current lifestyle and consider what adjustments you are willing to make for a dog. Getting a dog requires a firm commitment to responsible dog ownership. Remember that small dogs tend to be delicate and vulnerable. Being stepped on or mishandled can cause serious injury. Also, little dogs can be much more sensitive to colder temperatures, so be ready to help keep them warm. Some little dogs can develop furious attitudes, seemingly to compensate for their small size. Big dogs need a bit more space to play and move around in. Large, happy dogs with long, whip-like tails need "wagging space" to avoid tail injury or damage to household objects. Another consideration is expense: the larger the dog, the more expensive things like dog food, supplies and medical treatment.
