We have raised and bred Yorkshire Terriers for the past 12 years, and Maltese puppies for 6 years.  All of my dogs (puppies included) are fed homemade food made from scratch, with included vitamins, minerals, and probiotic kefir additives.  They are very healthy and exercise on a daily basis.  I also microchip all my puppies and provide the necessary information in regards to registering the chip number online or via mail.  If you have any questions in regards to the homemade food or the diet in general, don't hesitate to ask.
