Progesterone Breeding Information

There are multiple hormones that help to regulate the estrus (heat) cycle and pregnancy in dogs. These include:

  • Estrogen: Stimulates the ovaries to produce eggs.
  • Luteinizing Hormone (LH): Stimulates the ovaries to release the eggs.
  • Progesterone: Maintains a pregnancy.

Understanding how the hormone levels change can help in determining the best time to breed and when to anticipate whelping.

Most mammals ovulate when the estrogen level in the blood is increasing. Dogs, however, ovulate when the estrogen level is declining and the progesterone level is increasing. Estrogen levels can give us a general idea of when a dog will come into heat, but are not sufficient to determine when breeding should actually take place. Vaginal cytology can also provide some general information. Progesterone levels and luteinizing hormone (LH) levels are the best indicators of when ovulation will take place and when is the best time to breed. They are also useful in determining whelping dates, allowing an owner to reserve the appropriate days on the calendar and even to schedule a c-section (caesarean) weeks in advance.

Luteinizing hormone levels

LH is species-specific, meaning it is chemically different in different species. Blood testing for LH, therefore, needs to be done at a veterinary lab or at a veterinary clinic where access to the specific test for that species is available. Test results are generally available within less than 24 hours of submitting the sample.

The LH test needs to be done daily starting toward the end of proestrus. The LH spike typically lasts only 24 hours or less, so the test needs to be done every 24 hours in order to catch it. If the testing starts too late, the spike will be missed. The spike generally occurs 48 hours prior to ovulation.

Progesterone levels and breeding

The progesterone test is not species specific so the test can be run in human labs or veterinary labs. Results should be available in less than 24 hours.

The progesterone test can be done every 2-3 days starting about 3-5 days into the heat. Timing of the test can be more certain if the lengths of the dog's previous heat cycles are known. The beginning progesterone levels are typically less than 1.0 ng/ml until the day before the LH surge. The day of the LH spike, serum progesterone concentrations are 2-3 ng/ml; the day following the LH surge, the serum progesterone concentration is 3-4 ng/ml. Ovulation occurs at a progesterone level of 5 ng/ml.

Figure 2. Predicting Breeding Time And Whelping

Timing of breeding

The aim is to identify when the progesterone level reaches 2.5 ng/ml so the mating schedule can be set up, or the veterinarian and owner of the male dog can be notified that they should be prepared to collect and ship a semen sample. Depending upon the type of semen used, optimal times for natural or artificial insemination are:

  • Natural breeding should occur 3 days after the 2.5 ng/ml mark. Sperm in fresh semen survive 5-7 days after insemination.

  • Artificial insemination using fresh chilled semen should be used for a 1-time breeding. Insemination should take place 4 days after the progesterone reaches the 2.5 ng/ml mark or 48 hours after the 5 ng/ml mark. Sperm in chilled semen survive 48-72 hours after insemination. With artificial insemination, the semen should be deposited into the cervix to increase the chance of it being drawn into the uterus.

  • Artificial insemination using frozen semen should be performed 5 days following the 2.5 ng/ml mark or 72 hours after the 5 ng/ml mark. Sperm in frozen semen survives less than 24 hours after insemination. Frozen semen is ideally deposited directly into the uterus through surgery to increase the chance of pregnancy.

Fertilization and implantation

The sperm require a period of approximately 7 hours after ejaculation before they are capable of fertilizing an egg. This period is referred to as the "capacitation time." The egg also needs time to mature after it is ovulated, generally 48 hours from ovulation until it can be fertilized. Fertilization occurs in the oviduct (Fallopian tubes) regardless of the method of insemination. The fertilized egg then travels into the uterus but does not implant until 17-18 days after ovulation. If there are problems with the lining of the uterus, the egg may not implant or the placenta may not grow or be maintained. A normal placenta grows into the lining of the uterus. If implantation does not occur or the placenta does not grow normally, the fetuses are resorbed.

Progesterone levels during pregnancy and whelping

After ovulation, progesterone concentrations continue to increase for 2-3 weeks, finally reaching 10-80 ng/ml. This level is necessary to maintain a pregnancy. In the dog, the progesterone level will remain at this level for about 60 days whether or not the dog is bred, and whether or not she is pregnant.

About 48 hours before whelping, the progesterone level drops to the 2 ng/ml range and within about 24 hours of whelping, the level drops to the 1 ng/ml range. This can help determine the proper timing of a c-section, especially if the progesterone level or LH level were not used to determine the ovulation date. By correctly determining the whelping time, it can prevent puppies from being taken by c-section too early and thereby decreasing their chance of survival.

The following chart indicates the estrus cycle (by days), the hormone levels, breeding times, and whelping dates.

Before taking Rottweiler

Ротвайлерът стои здраво на земята, защото е уверен в себе си и се отличава с много здрава психика. Неговото добре оразмерено, компактно и яко телосложение издава голяма сила, подвижност и издръжливост.
Той е изключително бдителен защитник на своя стопанин, затова никога не бива да бъде провокиран, дори и на шега.
Видът му е естествен и грубоват, поведението самоуверено и безстрашно, но е добронамерен към децата и изпълнява предано  и послушно своите задължения.
Ротвайлерът, който е от "добро семейство" и е правилно възпитан, никога не хапе и не лае, защото според неговата "философска" гледна точка светът е твърде несъвършен, за да го заинтересува със своите преходни ценности.
Кучето е яростен индивидуалист и не се подмазва на никого. Освен това е много стиснато и ревниво и може да устрои истинска битка за своята топка или за обувката на своя стопанин. То ще разкрие нежното си и предано сърце само у дома, в семейството, насаме със своя стопанин. С него то играе и се прави на глупак, хитрува като малко кутре, стараейки се да увлече всички в своята игра.

breed standard

 Allgemeiner Deutscher Rottweiler Klub (ADRK) e.V.F.C.I.-Standard Nr. 147 /19.06.2000 /
Rottweiler
Translator: Mrs. Chris Seidler
Origin:Germany

Date of publication of the valid original standard:
06.04.2000

Utilization:Companion, servic and working dog

Classification FCIGroup 2 (Pinscher and Schnauzer type, Molossian type and
Swiss Mountain- and Cattle Dogs and other breeds)
Section 2.1 Molossian type, Mastiff type
With working trial.

Brief historical summary:
The Rottweiler is considered to be one of the oldest dog breeds. Its origin goes
back to Roman times. These dogs were kept as herder or driving dogs. They
marched over the Alps with the Roman legions, protecting the humans and driving
their cattle. In the region of Rottweil, these dogs met and mixed with the
native dogs in a natural crossing. The main task of the Rottweiler now became
the driving and guarding of the herds of cattle and the defence of their masters
and their property. This breed acquired its name from the old free city of
Rottweil and was known as the „Rottweil butcher’s dog".
The butchers bred this type of dog purely for performance and usefulness. In due
course, a first rate watch and driving dog evolved which could also be used as a
draught dog. When, at the beginning of the twentieth century, various breeds
were needed for police service, the Rottweiler was amongst those tested. It soon
became evident that the breed was highly suitable for the tasks set by police
service and therefore they were officially recognized as police dogs in 1910.
Rottweiler breeders aim at a dog of abundant strength, black coated with clearly
defined rich tan markings, whose powerful appearance does not lack nobility and
which is exceptionally well suited to being a companion, service and working
dog.
General Appearance
The Rottweiler is a medium to large size, stalwart dog, neither heavy nor light
and neither leggy nor weedy. His correctly proportioned, compact and powerful
build leads to the conclusion of great strength, agility and endurance.
Important Proportions
The length of the body, measured from the sternum (breast-bone) to the ischiatic
tuberosity, should not exceed the height at the withers by, at most, 15 %.
Behaviour / Temperament
Good natured, placid in basic disposition and fond of children, very devoted,
obedient, biddable and eager to work. His appearance is natural and rustic, his
behaviour self assured, steady and fearless. He reacts to his surroundings with
great alertness.
Head:
Cranial Region:
Skull:Of medium length, broad between the ears. Forehead line moderately
arched as seen from the side. Occipital bone well developed without being
conspicious.
Stop:Well defined.

Facial Region
Nose:Nose well developed, more broad than round with relatively large
nostrils, always black.
Muzzle:The foreface should appear neither elongated nor shortened in
relation to the cranial region. Straight nasal bridge, broad at base,
moderately tapered.
Lips:Black, close fitting, corner of the mouth not visible, gum as dark as
possible.
Jaws / Teeth:Upper and lower jaw strong and broad. Strong complete
dentition (42 teeth) with scissor bite, the upper incisors closely
overlapping the lower incisors.
Cheeks:Zygomatic arches pronounced.
Eyes:Of medium size, almond shaped, dark brown in colour. Eyelids close
fitting.
Ears:Medium-sized, pendant, triangular, wide apart, set on high. With the

Tail:In natural condition, level in extension of the upper line; at ease
may be hanging

Limbs
Forequarters:Seen from the front, the front legs are straight and not
placed too closely to each other. The forearm, seen from the side, stands
straight. The slope of the shoulder blade is about 45 degrees to the
horizontal.
Shoulders:Well laid back.
Upper arm:Close fitting to the body.
Forearm:Strongly developed and muscular.
Pasterns:Slightly springy, strong, not steep.
Front feet:Round, tight and well arched; pads hard; nails short, black and
strong.
