Dogs can suffer from a whole host of diseases and other serious health problems. Some of these conditions are inherited, while others are caused by viruses; still others are related to lifestyle and environmental influences.
All dogs need to be exercised everyday in some form or fashion. The most common method is through the walk around the neighborhood, but is a short walk around the block enough exercise for your particular dog?
Is there such a thing as the perfect puppy? In all likelihood there is not. There is always something one might change in any dog (or person really), but the goal should be to always strive towards raising a puppy to be its most perfect self. This is hard work, to be sure, but it is not only possible, it is necessary.
