Mating, pregnancy and childbirth. Small puppies should be cared for almost like children. A professional breeder does not have a regular working day, no days off and no indulgence, whether it is the morning after a grand holiday or the evening before a significant event. Regular (hourly) proper nutrition of puppies and bitches, washing, cleaning, sleepless nights, vitamins, vaccination. Then advertising costs, telephone bills, branding and registration of puppies, payment for mating with the owner of the dog, consultations with a veterinarian, and only after all this is the little puppy, with a veterinary passport and a puppy card, ready to go to a new owner.
