There are no credentials. They do not even need a medical certificate. They need not be sound either in body or mind. They only require a certificate of birth -just to prove they are first of the litter. You would not choose a Spaniel on these principles.
没有证书。他们甚至不需要医疗证明。他们不需要健全的身体或精神。他们只需要一份出生证明——只是为了证明他们是第一胎。根据这些原则，你是不会选择西班牙猎犬的。
