    I recently adopted Reese aka Tot from Patrick and Amy. Let me just say what a great experience it has been from beginning to end. The love and care they give these pups is nothing short of amazing. Reese has adjusted so well in the almost 72 hours we have had her. She is sweet, confident, and happy and I credit that to Amy and Patrick. They truly love these pups and want the best for them. If you are looking for a King Charles Cavalier look no further. Thanks again Patrick and Amy!

    Me and my wife have been looking for a Cavalier Charles Spaniel for about 5 months. Our son has been the owner of Jeffrey, this adorable and lovable Ruby red King Charles Spaniel, who turned 3 years in November. When Jeffrey and our son left out home to live in the separate place we felt so sad, missing the presence of somebody who loves you a lot. My husband wanted to see the dog who waits for you to take him out, enjoy a walk, then the breakfast after. We made the decision to have another dog like Jeff, but my husband has always wanted the black with beige color. I found Good Dog on the internet, and right from the beginning fell in love with Dinky , that Amy and Patrick showed. This wonderful family scheduled an interview with to get to know us before giving the dog for an adoption. We were impressed by their passion for all their dogs, It appeared they have been the breeders of them for quite some time. definitely, they wanted to ensure the dog finds a nurturing home and love with the new owners. Patrick McMahon spent a long time talking to us listening to our story, life, immigration to this country with our dog that we brought from Ukraine; Jeffrey who was raised by us and our son, and how we miss him terribly. Patrick discussed the diet, veterinary/insurance care, tried to answer all other questions. Obviously, he and Amy care very much about their puppies and all other dogs. They are indeed real dog lovers. Dinky grew up with people that provided an outstanding care for the puppies. They sent us the updates and pictures of him every day. On the day of delivery we met Amy and Patrick, very warma nd welcoming family. Needless o say they were a bit sad to give up the dog who had been with them for two months. They generously provided the toys, food starter, gave this lovely picture of our now Dinky with his parents, this comfortable blanket to wrap him up, the bowls, a tiny leash, colar, a certificate with this letter of recommendations what to do during our puppy transition. it looked like a fortune for Dinky our little bug, but the water from the well was a real gift! It was definitely love and safety for Dinky they cared more than money McMahom's family worried about. It was really very pleasant and unforgettable experience. We are grateful to Patrick and Amy for our new family member. The dog is just adorable, still drinking so well the well water !

    Patrick and Amy were wonderful to work with. Our Finely(Tyco) has adjusted very well to us already. He is a happy little guy full on energy and love. I was very nervous using a internet company like Good Dog, how ever they did put me in touch with Patrick and Amy and the process was very smooth. We asked if we could see the puppies along with mom and dad when Finley turned 7 weeks old. We were very warmly welcomed, actually they were happy to meet us as thy have a need to screen potential homes for their pups this made my wife and I very happy to see the care and thought that went into how they care for their puppies. Once we met Patrick, Amy and the puppies I was convince these were the people I wanted to get my puppy from. The pups were clean well care for playful it was very obvious they loved these little guys and had there best interest at heart. Finely is 10 weeks old as I write this he is 80% house broken he loves to play with his toys and just loves all the people (family) handling him. He is growing and thriving well, we can't be any happier with him. Thank You Patrick and Amy. I will send some photos.
