For the professional breeder, this is primarily a question of genetics. For the non-professional, it is also a personal question of whether you want the additional work, excitement, and involvement that goes with breeding:
1) finding a suitable stud.
2) mating the dogs.
3) special care for the pregnant female.
4) staying at home around the time of birth.
5) helping care for the puppies.
6) selling the puppies.

The financial aspect must also be considered. Sometimes there are stud fees, vet fees, and then no living puppies.

Nevertheless, breeding can be a most enjoyable and rewarding experience. The difficulties encountered before the birth of the puppies are forgotten when the joys of watching cuddly pups frolic, eat, and sleep begin. Also, watching your female suddenly and naturally become a fine mother is a heartwarming experience. The children can become involved with the care of the puppies if you want to make this a family project.

An important factor to consider is the timing of the birth of the litter. There are many responsibilities involved in the birth and care of the litter—indicating that much time and energy is needed in order to provide proper care. Keep in mind that the gestation period is from 60 to 63 days. After the birth, the mother usually takes good care of her puppies, but supervision is needed to make sure all the pups are healthy, eating well and resting enough. Once the pups are weaned, they must be fed several times a day and soiled newspapers must be changed often.

If the litter is more than two puppies, small whelping quarters are soon outgrown. Large breeds grow very rapidly and if they aren't sold by eight weeks, they need a sizeable area. Some novice breeders have had to give away fine dogs because they didn't have enough room to keep them until they could be sold.

Before you even consider whether you have the time, money, space, and patience to start breeding, the genetic qualities of your bitch must be honestly evaluated. If she has serious faults, it would be best not to breed her, as these faults would be genetically carried on to her young. If she has no basic faults and is a healthy dog with a pleasant temperament, breeding can be considered.

There is work, planning, cost, and effort involved if the job is going to be done correctly. If the true love of dogs and wishing to further the improvement of the breed isn't your main goal, then you really shouldn't go into it. For the amateur, there is usually little, if any, profit to be made. Most amateur breeders consider this their hobby and operate at a loss. To become a professional requires extensive experience and a sizeable investment in order to have quality breeding stock and the adequate facilities of a true business venture.
