Is it human to neuter a dog?

Castration - why?

"Castration and Animal Welfare" can that even be mentioned in the same breath?
The Animal Welfare Act explicitly allowed making the animal sterile (without giving reasons) - i.e. castration is part of the Animal Welfare Act expressly legal.

Animal Welfare Act § 6, Paragraph 1, Sentence 2, No. 5:

(1) The complete or partial amputation of body parts or the complete or partial removal or destruction of organs or tissues of a vertebrate animal is prohibited. The ban does not apply if (...)

5. (...) to prevent uncontrolled reproduction or - unless there are veterinary concerns to the contrary - Sterilization is carried out for further use or keeping of the animal.

Unfortunately, it happens that castration opponents no. 5 leave out, although this represents a falsification of the legal text in order to unsettle dog owners.

The castration is abroad (southern and eastern countries, also within Europe such as Spain) a contribution to active animal welfare. With castration campaigns an unwanted, uncontrolled animal population can be prevented and further animal misery can be avoided. Accompanying education in the relevant countries is imperative, because castration is still viewed as something unnatural and is rejected. Instead, the unwanted offspring are rather abandoned, abandoned and miserable to their fate, killed or given to a perrera (killing station).


Castrations in Germany, how can that be justified?
In Germany there was, and is, a successful education of dog owners on the subject of castration. Many dogs are now neutered, unwanted litters are rarely accepted. Opponents of castration claim, referring to the German animal protection law, that only cats with free access can reproduce uncontrolled, but not a dog under human control. In most cases, however, the drive is more dominant and stronger than human control. Many dog ​​owners are overwhelmed with the dynamics that develop from it and ultimately the animal suffers from human incompetence.
We see the enlightenment, "yes" - to castration "better prevention than killing", as animal welfare gain. Thanks to education, one no longer encounters foreign conditions in Germany: stray dogs without stray dogs that reproduce quickly (a bitch can litter twice a year) and then "have to" be killed.
In Germany, the avoidance of uncontrolled breeding with pedigree dogs and medical reasons for castration are now in the foreground. The neutered dogs are also easier to keep dogs in groups (e.g. in animal shelters, dog hotels, dog sanctuaries, dog schools, dog meetings), and precautions are taken against unwanted offspring at the same time.

What does a castration do?
With a castration theMales through a small, rather harmless procedure under general anesthesia, the testicles are removed and the spermatic cord is severed. In thefemale dog an abdominal incision is necessary to remove the ovaries and uterus (ovariohysterectomy). There is a possibility that the uterus and associated residual hormone production will be preserved. But the diseases that occur in an uncastrated bitch usually require the complete removal of the uterus and ovaries.


Every operation and general anesthesia carries a risk. Wound swelling and bleeding can occur and further treatments may follow.


Medical reasons for neutering a male dog

  • purulent inflammation of the foreskin
  • Changes in the testicle
  • One-earedness (testicles remaining in the abdominal cavity)
  • various tumor diseases
  • recurring problems with the prostate and rectum
  • massive stress from hot bitches in the neighborhood
  • massive stress from uncastrated "rivals" in the neighborhood


Medical reasons for neutering a bitch

  • Mammary tumors (mammary tumors) *
  • Pseudo-pregnancy stressful for the dog **
  • Inflammation of the uterus (endometritis) ***
  • Ovarian tumors or cysts
  • Ovarian diseases associated with menstrual cycle disorders and impaired fertility (prolonged heat or greatly shortened cycle)
  • Vaginal prolapse (due to hormonal influence, excessive thickening of the vaginal mucous membrane occurs during the heat and the tissue "falls" outwards between the labia)
  • Diabetes mellitus
  • Hypothyroidism (prolonged cycle)
  • Cushing's disease (prolonged cycle, infertility)
  • cycle-dependent behavioral disorders (aggressiveness)

* Regular palpation of the nursing bar is necessary in order to Mammary tumors to be recognized in good time (usually occur from the age of 9). If malignant tumors are recognized too late, metastases are very often found in other organs. With early castration (before the first heat) the risk of developing breast tumors decreases to zero, while hormonal heat suppression favor this.

** one Pseudopregnancy is based on evolutionary history: Only the female lead wolf (alpha bitch) is mated and has young. The other bitches in the pack produce milk to ensure that the puppies are adequately fed. Pseudopregnancy can severely restrict the bitch physically and mentally and in such a case become pathological.

*** One Uterine inflammation often only shows up at an advanced stage - when you recognize them, it is already too late for some bitches. The older the bitch, the more likely it is to develop uterine infections. The suppuration of the uterus restricts vital functions and poisons the body from within. Even in older bitches, this risk is to be assessed as higher than the risk of anesthesia. Experience has shown that it is a liberation especially for the older bitches and they literally bloom when the desolate uterus body is removed.

Despite plausible arguments
castration of the dog often leads to emotional discussions. Interestingly, the question does not even arise in the case of the children's rabbit, the horse and the house cat. The castration of the dog, however, must often first be discussed in the family council or with some veterinarians. 


Frequently asked questions about castration

Isn't sterilization more sensible and gentler for the dog?
No, Sterilizations (cutting the germ path to the gonad) are often associated with complications and re-operations in bitches. In addition, the sexual instincts are retained after sterilization. Sterilization is not recommended from a medical point of view or from a welfare point of view and is rarely practiced.

Spayed dogs get sluggish, fat and boring?
No, the owner is responsible for the weight of his dog. If it is too thick, the feed must be reduced. The holder can also control the amount of movement. A spirited dog does not become a sleeping pill after castration and a stoic dog does not become a movement clown afterwards. In principle, the dog should not be compared with humans, not even the symptoms after neutering.

Will my dog's coat change?
, hair growth is controlled by hormones, which can lead to changes in the condition of the coat. But here too, a black dog does not become a white dog, and a short hair does not become a long hair.

Are reasons to ease the posture acceptable arguments?
After the male's castration, the production of testosterone decreases. This hormone ensures, among other things, the "willingness to fight", the elimination of the competitor for his own reproduction. A castrated male can inflate himself just as aggressively as before, but basically takes away his ambition Fight the fight to the bitter end. And since we live with our dogs especially in metropolitan areas in a confined space, this relaxes everyone involved. Sexual behavior decreases in males: there is no restlessness and wolf howls, the food tastes good again and stray becomes uninteresting. In bitches, one should avoid straying (looking for potent males) and unwanted offspring, especially when males and bitches are kept together.

Can errors in upbringing be alleviated by castration?
Yes and no
. Behavioral problems that are not controlled by hormones persist even after castration. Mistakes that the dog owner has made in the upbringing are not eliminated by castration. So the dog, mobbing on the leash, remains yapping. The interest to stay with the owner (or her own pack) and the obedience to recall can be improved after castration - the hunting instinct remains unchanged

Sexually mature dog, what does that mean for dog and owner

The female dog usually comes into heat twice a year (interval: 6-7 months on average) and is then ready for reproduction.
This means for dog and owner: Isolation twice a year to avoid unwanted offspring. You have to reckon with visits from "dearest" males waiting for their opportunity in front of the front door.

The Male is ready to mate all year round after reaching sexual maturity.
This means for dog and owner: Lying in wait all year round to avoid positioning battles and unwanted offspring.

Is the Male Sexually mature, pubescent, his sexual interest increases and the first attempts at mating are carried out, the marking behavior begins.
This means for dog and owner: the instinct is presented to the game, i.e. the ball game or the like, becomes uninteresting when an interesting bitch or male "rivals" appear = falling obedience.

In the female dog Sexual maturity becomes visible through the first heat (heat), sometimes only recognizable through intensive licking of the genital region, noticeably more urinating (marking) and interest in and from males.
This means for dog and owner: 3 weeks of isolation, the drive is presented to the game, i.e. "woman seeks man" = declining obedience.

In contrast to us humans, an aging bitch shows a sexual cycle until the end of her life. So a bitch does not go through "menopause". The cycles of their heat are, however, less pronounced, at larger and sometimes irregular intervals.
This means for dog and owner: Isolation twice a year for a lifetime (or less often in old age).


Additional info
The bitch's cycle phases

  • Fervor, first phase of heat, swelling of the pubic area (vulva), bloody vaginal discharge (bleeding), duration between 3 and 20 days 
  • Heat, The bitch is ready to mate ("standing phase"), the tail is turned sideways and the back is pressed in, the pubic area swells, vaginal discharge becomes slightly pink to colorless,

Pre-heat and heat form the heat of the bitch and last an average of 3 weeks.

Dog breeds that remain small reach sexual maturity earlier than representatives of large breeds (males between the 5th and 8th month of life, bitches between the 6th and 12th month of life).
