19. Yorkshire Terrier
The Yorkshire Terrier is one of the prized toy dogs that melts people’s hearts. Their cheerful disposition and cute looks make it easy to fall in love with this dog. They started out as rat hunters in mines and texture mills, and that trait has continued throughout the years, giving them a high prey drive. They have quite a big personality in that tiny body and aren’t afraid to be vocal about it. They’re loyal to their owners and make great alert dogs when a stranger is on your property. They’re not big shedders, but you should brush them on a regular basis to keep their coats looking nice.
