rottweiler dog breedsrottweiler was in the time of the racing establishment working dogs, which preferentially with the butcher's trade was to be found. They had to be strong and vigilant, big and they were allowed to be massive, as they sat directly at the meat pots of the place.
with the collection of the typical representatives, the foundation of a breeding association, the formulation of ´Standard´ of the breed type and with the regimentation of the breeding has become
a breed development with show business and dog sport was initiated, to whose end point we today. The focus of the breeding goal has changed and must continue to be because the social environment into which rottweilers are bred is also in change.
Dimensions and weights:
Apart from the characteristics of the body, its proportions are a visible sign of Change. In general, it can be said that precisely by pointing at the exhibitions, breeding approvals, and approvals, a dynamic is created that drives the breeds Big breeds become bigger and bigger, heavier breeds more and more powerful, short snouts more and more short-snouted wrinkled always wrinkled! Once a character is in the target catalog, then is turned indirectly on the screw. This goes all the way to the deplorable over-typification with animal welfare relevance.
It is, therefore, appropriate to take stock of size and weight. Data processing allows access to measurements from the last two decades. Unfortunately, representative comparison with the founder animals is not possible. There one becomes on narratives and old reports.
how big is a rottweiler?breeding suitability tests and approvals were carried out during the investigation period of the last 25 years a total of 7099 rottweilers measured and weighed. among them are 2885 males and, because of the higher need for breeding bitches, 4214 bitches. after that males with 65,3 cm around 5,5 cm bigger than bitches, who measure only 59,8 cm, with 65,3 cm. they reach so only about 91% of the males. that applies naturally only in the average! shows the range of variation of males and females.
the height of the columns shows how many animals the respective shoulder height. The difference between the sexes, but also the overlap clearly. There are big bitches that are much bigger than some males.
The fact that bitches are biologically five and a half cm smaller than males often deceives the breeders. (and judge). They prefer big bitches, which are similar to the stately type of male. are without taking into account that the sons of them have the potential for 5.5 cm more received. The effect on the entire breed may not be very great, but year after year a half a millimeter will be an inch more in 20 years.
What is the trend really like? shows the average height at withers from 1982 onwards. is depicted. The data are on dogs of German breeding of the last 25 birth cohorts. of which 23 volumes have already been measured. There are some coincidental differences between the vintages, but the overall trend shows us that development is not is dramatic. With males, the three vintages 1982-1984 are 65.1 cm tall on the average, then the last three vintages measured 2002-2005 yield 65.3 cm.
These 2 millimeters are certainly not worth mentioning. For bitches, the comparable numbers are 59.5 cm and 59.6 cm, which means no change! Although there is a slight upward trend around the year 2000 This was, however, reduced again in recent years. This shows that the mechanisms to exclude oversized dogs from breeding, effectively Check size trend. It becomes clear from. that males over 68 cm in height are practically the breeding admissions do not appear, likewise, bitches over 63 cm are hardly represented. These are the size limits of the standard, which is also 56 cm or 63 cm below.
barriers set. critical readers will derive from the graph that the rottweilers, in reality, are larger because the preselection for breeding approvals distorts the picture. Since the but I'm sure it's the same every year, the trend is correct.
the rottweiler captivates not only by his size but also by his massive body mass, which can be well described by the chest circumference. male and female dogs are is shown with its frequency distribution. They also differ in this characteristic clearly, about 6,06 cm, with males having a chest circumference of 88,04 cm and bitches of 81.58 cm. the range of variation is enormous. Males show e.g. values of from 77 cm to over 100 cm, bitches from 65 cm to 95 cm. Contrary to the stable size development, a clear change is visible over time.
bone strength, muscle mass, height, and width, all of which ultimately determine weight. At the ZTP events, males weigh 47.6 kg on average, bitches only 39.3 kg. on the scales. The variation and frequency of individual weights are shown can be seen. Here, too, the overlapping of the sexes becomes particularly clear. It becomes obvious how difficult it is for bitches to compete in males.
if they're just normal size and heavy.
the distribution of the weights is not, as with the size, circumcised, but rather shows the typical biological normal distribution, which also exists for the characteristic chest circumference. breeding blocks via the height at withers thus has hardly any effect on chest circumference and weight. This also has an effect on which shows an increase in weight shows the weight trends are shown separately by gender. in males, there is a constant upward trend, while it begins with bitches only in the middle of the nineties clearly.
Consequences and risks:
Type development on the one hand and absolute mass and weight ratios on the other are not without risk. size and weight cannot be achieved without growth, and growth, if it happens too fast or even through too energy-rich feed still has fatal consequences for skeletal development. Damage, for example, elbow arthrosis (ED), pre programmed. visible damage is caused by joint inflammation (arthritis), cartilage damage (osteochondrosis) or ossification disorders (isolated Processus anconeus). frequent are also burst-offs unripe bone parts (FCP) due to overloading and incorrect loading as a result of unregulated growth spurts. the fact that males with significantly stronger growth than females also have significantly more ED problems, supports this statement.
In a study on HD and ED, weights were recorded during X-rays. This date is usually before breeding. Also with this weight the bitches (37,79 kg) clearly lighter than the males (45,36 kg). Although the weight during X-rays in old age between 12 and 15 months, only the average growth benefit and not necessarily the increase in critical juvenile development up to the 6th month (phase of the ossification), there are nevertheless indications of a reference to the ED: with increasing yearling weight, especially in males, the weight correlates with elbow dysplasia.
in the range of the weights of the bitches the influence of the to ED not yet obvious, but with males, which react apparently more sensitively, is with the high body weights from 50 kg, a drastic increase in ED to record. This concerns 32% of males, but only less than 1% of bitches. ED control is not only a breeding problem but also primarily a question of prudent Breeding.
Significance for the future:
The rottweiler dog, after 100 years of breeding work, shows himself today in his stately stature of 65 cm and a body mass of 45 kg. The variation around these values is considerable and ranges from 58 cm to 71 cm or from 34 kg to 66 kg. Females are correspondingly lighter and reach about 91% of the height and 82% of the weight of their brothers.
dogs are bred for humans. these must be able to deal with it and the strength and temperament. if the circle of those who are in contact with the rottweiler can deal physically and characterwise with getting smaller and smaller, the niche will also be for the rottweiler in our society more and more closely. That would be a pity! The standard, like also always he is deposited with the FCI, and his interpretation is to the rottweiler in health and social acceptance, then a further 100 years for the rottweiler.
