| Breeding process and the Natural breeding of the German
shepherd dog |

Ovulation timing: Ovulation timing is typically performed by
measuring the bitch’s serum progesterone concentration. Progesterone is
measured serially every 1-3 days to indirectly determine when the LH surge
and ovulation have occurred. Ovulation timing should begin very early in the
cycle of a bitch that has never been bred before or that has been bred
unsuccessfully in the past. Ovulation timing can begin later in the cycle if
the bitch’s reproductive history has been previously established.
Progesterone will be low at the beginning of proestrus and will increase to
1.6 – 2.0 ng/ml at the time of the LH surge. At ovulation, progesterone
concentrations reach 4.0 – 10.0 ng/ml. Progesterone concentration continues
to increase until approximately 25 days after ovulation and then decline
over the next 30-40 days.
Breeding management with natural mating: Breeding our German shepherd dogs naturally is the
most successful method we use. The process is to
introduce the female to the stud dog every other day while she is in
heat until she is ready to invite the stud for mating. The female should be
bred every other day until she will no longer stand for the stud.
Although this is usually highly successful, it should be remembered that
some bitches will ovulate after being in heat only a few days and others
ovulate after being in heat for several weeks. In addition, some bitches
will refuse to stand for the dog, even when in estrus. Ovulation timing
allows the breeder to more accurately determine when the bitch should be
bred and also allows the breeder to accurately determine when the bitch is
due to whelp.
Breeding management with fresh semen artificial insemination:
Some breeders choose to have artificial insemination (AI) performed even
when the dog and bitch are both readily available. Typically, some ovulation
timing is performed to minimize the number of AIs that are performed and to
ensure they are performed at the optimal time. When using fresh semen, the
bitch is inseminated anywhere from 24 hours before to 48 hours after
ovulation. Two AIs are generally performed 48 hours apart. Fresh semen has a
very long life span in the uterus (5-10 days).
Breeding management with shipped-cooled semen: The use of shipped-cooled semen allows breeders to breed to stud dogs
located in different parts of the country or even other countries without
having to ship the bitch. Ovulation timing is performed and semen is ordered
to arrive 3-4 days following the LH surge and again about 48 hours later.
Cooled semen has a relatively long life span in the uterus (3-4 days).
Breeding management using frozen semen: Ovulation timing is
essential when using frozen semen. Ideally, 2 intrauterine inseminations are
performed 4-5 and 6-7 days after the LH surge. The semen is thawed
immediately prior to insemination. Intrauterine insemination is necessary
for success. |

| The getting ready to breed phase (estrus) can vary from
female to female in accepting the male for mating , this depends on the
ndividual females desire to mate and her time period. |
