Reproduction in dogs - season, heat, oestrus, pregnancy tests
Puberty or sexual maturity in the female dog usually occurs around six months of age. The smaller breeds tend to go into oestrus or "heat" earlier and some females can have their first "heat" cycle as early as four months of age. On the other hand, the large and giant breeds can be up to two years old before they come into heat for the first time.
Pregnancy and your dog - an overview
Pregnancy (or the gestation period) in bitches normally ranges from 58 to 65 days with an average of 65 days. Individuals may vary but you should inform your veterinarian should your bitch exceed 65 days.
Breeding - What to expect after mating
Pregnancy, also called the gestation period, normally ranges from 58 to 65 days with an average of 63 days. With a planned breeding, the date of mating should be carefully recorded. If there are two matings, make a note of the exact dates and expect birth to occur between 63 and 65 days later.
Breeding - Whelping or Birth
From the time of mating, many females will show changes in behavior, often becoming more affectionate. However, some pets will become uncharacteristically irritable and may even act aggressively during pregnancy. Be sensitive to your pet's behavioral changes and be sure to alert your veterinarian if you observe any abnormalities that you are uncomfortable with.
Breeding - Birth Problems
Although the majority of dogs will give birth without the need for veterinary assistance, problems can arise which require veterinary attention. It is important to closely monitor your pet during birthing and seek veterinary care if you have any concerns.
Breeding - Rearing Puppies and Caring for a Mother
For the next two months, even if everything went smoothly with the birth, you have a lot of work to do! After the birthing process, clean up the mother as much as possible without upsetting her. Remove any of the soiled newspaper or bedding from her whelping box.
Breeding - Growing, Lactation, Weaning
During the first three weeks of life, puppies require little care from the owner provided the mother is doing her job. Puppies are born with their eyes closed but the eyes open after one to two weeks. If any swelling or bulging is noted under the eyelids, they should be gently opened by massaging with a cotton ball dampened with warm water. If the swelling is due to infection, pus will emerge as the eyelids open and it is important to contact your veterinarian.
Breeding - Finding Homes & Vaccinations
Most puppies can be placed in their new homes at around eight weeks of age. Puppies should remain with the litter this long to ensure proper weaning and social development. Puppies that are taken from the litter and mother earlier than this are known to have an increased amount of behavioral problems.
