In fact, you can never be sure that your puppy is healthy and good-tempered if you purchase it for little money. That is why our strong recommendation is not to buy a cheap puppy.  Unregulated breeding can result in severe hip dysplasia which is passed from parents to their offspring. This health condition can display at the very young age of a dog - often under 4. This is a result of a loose position of the hips in their sockets. The looser the sockets are, the more profound severity you will observe. Some dogs may display a limp even at the age of 2 or under.  Therefore, find a responsible and reputable breeder, and you will be sure that your puppy is really healthy. You will get a loyal friend and beloved companion for a long time then. So, don’t try to save on the puppy. It is always a bad idea.
