The Kienlen's are professional, responsible breeders. Munchkin is a therapy dog and goes in hospitals and nursing homes to cheer up the patients and staff. She has a routine of going on her own to each door and walks in a few steps. If the patient encourages her, she proceeds and allows the patient to pet her. If they are not interested, she leaves and proceeds to the next room. We never taught her this, she is just sensitive and well balanced emotionally. All our dogs have been wonderful, but she is the very best! Even our vet commented - "you really got a great dog this time." I don't know why those people are ranting so. After all they got their money back. Some people are just trouble makers. We are truly blessed that we found the Kienlen's. the Cairn puppy that we purchased from them is - hands down - the best dog we have ever owned. She is nine years old now and we have never had any problem whatsoever. She is smart, loving, friendly and she sleeps with us every night.
