Please research any breed you are interested in before purchasing a precious puppy from anyone. A puppy/dog becomes part of your family and it is very sad for one to be given up due to incompatibility problems that could have been prevented by an owner being responsible and doing their homework. Doing extensive research will help insure that you will choose a breed that is compatible with your lifestyle and that you will be happy with for all of its life. It is very sad and stressful for the dog/puppy who is given up by his family.
So, keep in mind that purchasing a puppy is a lifetime commitment - at least the lifetime of your dog. Dogs usually live 12-16 years.
