Hallo PUma,
ich habe da folgende "Erklaerung" der amerik. Tiermedizin beizufuegen und da wir uns an diesem Thema hier sowieso schon zu Tode diskutiert haben, spar' ich mir die Uebersetzung. :-))(...ist irgendwo im Archiv 'vergraben" )
Ich kann nur sagen, dass in den USA jaehrlich ueber 4 Millionen Hunde und Katzen eingeschlaefert werden, weil Leute kein Verantwortungsgefuehl haben und ihre Hunde sich wie die Karnickel vermehren koennen.
Und fuer jeden "gezuechteten" Mischling muessen tausende von Tierheimshunden ihr Leben lassen, da hier in der Regel Hunde und Katzen, welche nicht adoptiert wurden nach 10 Tagen TH eingeschlaefert werden.
Leider gibt's halt noch viele Leute, die gerne einen Wurf von Fiffi haben wollen, weil Fiffi und Finchen zusammen ja soooo suess aussehen... :((((
An die Konsequenzen denkt dann leider in dem Moment keiner....
Das tolle ist jedoch, dass jeder Hund, der hier vom Tierheim adoptiert wird kastriert werden muss und das jeweilige Tierheim die Rechnung zur Haelfge uebernimmt. Ausserdem gibt's auch Tieraerzte, die Sonderpreise anbieten.
Gruss,
BINE
Und hier nun der englische Text:
When an ovariohysterectomy (OHE) is performed prior to the first heat period in a female dog, the risk of mammary cancer later in life is less
than 1%.
When OHE is performed between the first and second heat periods the risk is about 8% of mammary cancer later in life.
Anytime after the second heat period the risk of mammary cancer in female dogs is about 25%, whether an OHE is performed later, or not.
This is perhaps the strongest
argument for spaying female dogs.
The other major medical risk to female dogs that can be avoided by OHE is pyometra. This is infection of the uterus and it occurs in roughly 8% of female dogs sometime during their life time.
In dogs uterine infections are a greater risk than in other species, due to the unusual way in which dogs have estrus cycles. The long interval between cycles with a closed cervix
leads to severe infections developing with minimal clinical signs and so
the condition often is life threatening at the time it is discovered.
The disadvantages of spaying female dogs include a slight increase in
aggressive tendencies in some females after OHE, an increased risk of
urinary incontinence (usually treatable but may require life-long
treatment), weight gain above what would occur with normal maturity in
about 10% of dogs and the risk of the surgery itself. The surgical and
anesthetic risk of death in a fairly large study done in Canada was
reported to be about 1 in 500 for dogs in the study.
For male dogs, the benefits of neutering (orchiectomy) are not quite as
compelling, although it does decreased the risk of prostate hypertropy and
infections pretty significantly and if the dog is going to be allowed out
unsupervised it does help to keep the dog home and to avoid complications
associated with seeking out females in heat, such as being hit by cars,
shot by angry female dog owners (maybe only a U.S. problem?) and fighting
with other suitors of the female in heat. Neutering makes urine marking less
of a problem with many pet owners consider to be a major benefit, as
well. There is about the same problem with weight gain, dogs neutered
early may grow larger than they would have otherwise and there are surgical
and anesthetic risks.
Overall, I think that it is best to spay female dogs because it really
seems to help them live longer. I think that neutering male dogs often
provides a better life style for them and that in my practice area this
benefit outweighs the risks.
