Perfect House Of Pugs acquired a passion for animals, and the Pug puppy in particular, at a young age since I grew up in a house with lots of dogs. It was a natural ability to know how to grow, nurture, and care for animals. I knew what the future held when I met my wife, who essentially had the same enthusiasm as I have. Being a breeder is more of a passion for me than a profession since I get to witness people's faces light up when they successfully adopt a pug puppy from our facility. It is not possible to find happiness in anything else. PLEASE VISIT OUR WEBSITE LINK BELLOW FOR MORE INFORMATION ABOUT PUG PUPPIES.
