Quais as DESVANTAGENS em castrar um cão?

[gasparbelga]

também foi castrado a conselho do Vet.. não podia ver um macho atacando-o. Há uns 2 meses foi a gota de água, quando com todas as cautelas abri o portão, numa brechazita ele viu um Pastor Alemão a passar. Nem queiram saber, o Gaspar teve que ser operado e aproveitou-se estar anestesiado para o fazer. Ainda não vejo que esteja mais calmo, continua brincalhão como sempre, mas só o solto à noite com tudo já fechado. Nunca mais arrisquei a abrir os portões com ele solto. Ele nunca saía, mas naquele dia... fiquei em pânico por ele, pelo outro e por mim que gastei uma pipa de €€

[moslie]

Eu acho piada num país onde os canis estão cheios e mais parecem um filme de terror, onde nas terreolas os cães andam nas ruas em bando e morrem na estrada e ninguém vai buscar o corpo, as pessoas afogam e enterram as ninhadas e prendem os cães a árvores com meio metro de corrente e depois fala-se em castrar e fica tudo muito chocado!
Nunca vou perceber, as pessoas queixam-se que nem para elas tem dinehiro para médico e comida, mas no entanto deixam os animais reproduzir à vontade.
E castrar é uma maldade!

Olhe que nas terrinhas os cães são felizes, apesar da vida curta e de não serem tratados como os da cidade, segundo dá a entender das suas palavras.
Repare: Andam soltos (não nasceram com trela)
Comem Raw, cozinhado, encontrado, enfim, tudo o que eles gostam e nós não gostamos de lhes dar (por norma ou impossibilidade)
Não têm necessidade de tratamentos dolorosos no fim da vida deles, pois a natureza encarrega-se de chegada a altura os "transformar"
Tinha um cão que andava aqui perto, que tinha casa, e dono, mas o teimoso do cão andava sempre fora de casa. Saltava tudo e mais alguma coisa. Era feliz fora. Não dentro dos muros do jardim. Lá andava ele durante o dia, e recolhia-se à noite no pinhal perto de casa.
Esta é a mais pura atitude do cão. Depois vem o lado humano. O que lhe faltava era mimo. muito gostava ele que o acariciasse. Talvez se o dono o fizesse ele gostasse de estar dentro de casa. Quem sabe.
A minha cadela não sai de casa sem mim mesmo que eu deixe a porta aberta. O meu cão, se pudesse, era um vadio.

[gasparbelga]

mas não tenhamos ilusões, na minha opinião qualquer animal, mesmo bem acariciado, bem tratado, se o dono deixar dará umas escapadinhas. Eu ía dizer que era humano... perdoem-me, mas é natural. Então também não gostamos de sair, de arejar e por vezes sózinhos, ou não??!! Já sei já lancei a confusão. Vamos a isso...

Concordo que grande parte deles, caso possa, dê uma escapadela. Mas não podemos generalizar. Pela experiência que eu tenho com cães, os meus não são felizes sem mim. O cão que tenho agora é solto em locais apropriados diariamente e se não me vê, entra em pânico. Pode ter todas as oportunidades para se por a andar, mas não o faz. Acho que a felicidade dele é à minha beira, se poder estar no meu colo ainda melhor

Quanto ao tópico, aconselho a forista a passar neste site, onde certamente encontrará parte das respostas às suas dúvidas: http://www.esteriliza-me.org/saude

[capuxinhu]

O meu foi castrado com 2anos por aconselho do Vet, eu também não estava interessada que ele andasse nas meninas por isso segui o conselho dela.

Não vi muitas diferenças continuou o mesmo energético e não engordou nadica (Acho que também porque fazia exercicio fisico).

Olhe que nas terrinhas os cães são felizes

Essa é a sua perspectivas, segundo a sua teoria cães abandonados à mercê de atropelamentos, doenças, causar acidentes, poderem ser atacados ou atacar etc.. são felizes pois....

Repare: Andam soltos (não nasceram com trela)

E suponho que nascem em apartamentos, educados por pessoas, a perceber como funciona o mundo dos humanos? Essa perspectiva de "natural" é caricato!

Comem Raw, cozinhado, encontrado, enfim, tudo o que eles gostam e nós não gostamos de lhes dar (por norma ou impossibilidade)

Raw Diet não é o mesmo que comer lixo ou o que encontram!

Não têm necessidade de tratamentos dolorosos no fim da vida deles, pois a natureza encarrega-se de chegada a altura os "transformar"

POis quando ficam doentes simplesmente morrem por negligência de cuidados médicos, não precisam de tratamentos realmente....

Esta é a mais pura atitude do cão

É? Ele disse-lhe ou é a sua conclusão? É que a pura atitude de alguns cães e morder pessoas que passam em frente ao terreno deles ou matar cães que se cruzam pelo seu caminho, isso também é puro e natural acha bem?? Sabe o que é a domesticação?

Depois vem o lado humano. O que lhe faltava era mimo. muito gostava ele que o acariciasse. Talvez se o dono o fizesse ele gostasse de estar dentro de casa. Quem sabe.

O lado humano nunca se poder resumir a mimo (seja lá o que isso for) mas a assegurar os cuidados de bem-estar do cão.. que infelizmente cada um tem uma noção hiper deturpada do que isso poderá ser...

A minha cadela não sai de casa sem mim mesmo que eu deixe a porta aberta. O meu cão, se pudesse, era um vadio.

O seu cão é agressivo e problemático e deve ser responsável por ele e a sua cadela também é sua responsabilidade e sinceramente a minha intenção com estes comentários é apenas alertar que a senhor percebe muito pouco do que os cães e o mais ridículo é que sabe disso mas insiste em dizer baboseiras destas e vem já a seguir dizer que a sua opinião blá blá, mas saiba que aquilo que aqui diz faz tanto sentido como as pessoas que colocam cães em correntes e dizem que os cães são felizes porque são de guarda e estão a trabalhar o dia todo. Pense bem nisso e reconsidere as suas noções do que PENSA saber sobre cães.

ao invés disto porque não sugere alguns textos de pessoas que lidam com cães, sejam lá quem forem?

Para quem começou o tópico, desculpe o off-topico mas aqui fica um link que poderá elucidar acerca do tema da esterilização:

http://www.esteriliza-me.org/

Em baixo deixo um texto em inglês não encontro em português, o texto é grande mas copiei apenas a parte que fala das desvantagens e dos mitos. Espero que ajude (tem no final uma nota do autor relativamente ao discurso do "é natural o cão fazer isto e aquilo" que espero que ajude também)

POINTS AGAINST STERILIZATION

1. Dogs may gain weight after being altered.

It is true that some animals may tend to gain weight after they are sterilized (Fettman 1997, Root 1995). The removal of the sex hormones may tend to slow an animal's metabolism somewhat (Flynn 1996), although some studies have found no differences in weight between intact and sterilized animals (Salmeri 1991a).

However, many dogs are altered just as they are reaching maturity. At this time in their lives, even dogs who are NOT altered will be gaining weight and slowing down a bit, so any change you see in your pet may not have anything to do with being sterilized. If you DO notice a weight gain after your dog is altered, simply decrease the amount of food you are feeding and increase the exercise your dog gets every day.

2. Altered dogs may be taller than intact dogs.

It is true that dogs who are sterilized before they have reached full maturity may be slightly taller than they would be if they had been left intact. Sex hormones influence the end of bone growth after puberty. Since the sex hormones never arrive in dogs which are altered before maturity, the bones tend to continue growing for longer than they would in the intact dog. However, this difference is very slight overall -- and the dogs being altered are NOT show dogs, so a little extra height is of little significance. Also, there does not appear to be any difference in size between puppies sterilized very early (6-10 weeks) and those altered later (7 months) (Crenshaw 1995, Lieberman 1987).

3. Sterilized dogs may become incontinent.

Some altered dogs may develop a problem with controlling their urine output. This is especially likely in females, but may also happen in males (Aaron 1996, Arnold 1997a). It is thought that this problem arises because the loss of sex hormones affects the strength of the urinary sphincter muscle (Gregory 1994). One researcher has claimed that incontinence may occur in as many as 20% of all spayed dogs (Arnold 1997a), but other vets believe this rate is much lower (Thrusfield 1993).

Fortunately, the problem may be as minor as a few drops here and there, and it is usually easy to control with inexpensive drugs such as phenylpropanolamine (Arnold 1997b, Heughebaert 1988). Sometimes estrogen replacement may be necessary. Incontinence problems may last for the rest of the dog's life. However, incontinence may also disappear after a few months or a few years (Heughebaert 1988, Arnold 1989). Also, keep in mind that older dogs will sometimes develop incontinence even if they are left intact, so incontinence is not always related to sterilization.

4. Sterilized dogs are more likely to have problems with hypothyroidism.

A few dogs, especially bitches, may be more likely to have problems with decreased thyroid function after they are altered (Panciera 1994). Fortunately, thyroid problems are easy to treat with inexpensive thyroid supplements. Also, some intact dogs will also experience hypothyroidism, so most cases of hypothyroidism are not actually due to being sterilized.

5. Bitches who are aggressive before being spayed may become more aggressive after being spayed.

This appears to be a valid concern for owners of aggressive bitches (O'Farrell 1990). However, it's an easy problem to avoid. If you have an intact bitch who is already aggressive, think seriously about letting her remain intact. If your intact bitch is NOT aggressive, spaying her is not likely to MAKE her aggressive.

6. Sterilization, especially spaying, is an invasive surgical procedure.

There are risks involved with any surgery, both from the surgery itself and from the anesthetic agent. However, the rate of complications is very low, and serious complications are especially rare. Especially with newer anesthetic agents like isofluorane and newer suture materials, there are rarely any serious problems. Significant complications of sterilization surgeries occur in roughly only 1-4% of surgeries (Pollari 1995, 1996). Also, the surgical procedure actually appears to be *safer* when performed in younger puppies, with less serious complications occurring overall in young puppies than in puppies altered at later ages (Fagella 1994).

7. Sterilization is expensive.

Surgical costs may be as low as $25 or as high as $300, depending on the size and age of the dog, whether the dog is male or female, and the area of the country in which you live. There are low cost spay/neuter clinics in many areas these days for people who can't otherwise afford the procedures. And in some areas you will actually SAVE money by sterilizing your dog, if licensing fees are lower for altered pets.

8. The size of the external genitals may be smaller in dogs who are sterilized before puberty.

The penis of the male and the vagina of the female may be somewhat smaller in dogs who have been altered before puberty (Salmeri 1991a, 1991b). However, it is usually of little functional consequence to the dog. In a breed which is predisposed to urinary tract blockage, such as male dalmatians, this may be a problem; but in most breeds this is not likely to cause any medical complications. Very occasionally, bitches who were altered at very young ages may develop some skin irritation in the vulvar region (Jagoe 1988), but this also is not a common occurrence.

MYTHS ABOUT STERILIZATION

1. A bitch ought to have at least one litter, or at least one heat, before being spayed.

The chances of mammary cancer in bitches gets much lower when they are spayed before their first heat, as discussed above under "points for sterilization". Spaying a female before breeding her eliminates the chances of medical problems during a pregnancy or during birth or while rearing puppies. Also, puppies sterilized when they are very young (even as young as 7 weeks) actually have FEWER problems with the surgery than dogs who are neutered later (Faggella 1994, Howe 1997).

Before you let your dog "have just one litter", spend some time volunteering at your local shelter and see all the puppies and dogs who must be killed daily. Letting your dogs breed only adds to the death toll, and to the vast numbers of dogs already suffering from genetic diseases like hip dysplasia, von Willebrand's disease, progressive retinal atrophy, and many other diseases which can only be avoided by careful planning BEFORE breeding.

2. Castrating male dogs makes them more likely to get prostate cancer.

No, this is not true. There is apparently NO significant difference between the incidence of prostatic adenocarcinoma in intact males vs castrated males (Obradovich 1987). The only difference is an increased spread of the cancer to the lungs of the neutered dogs (Bell 1991). And MOST types of prostatic disease are ELIMINATED by castration, as discussed above (Krawiec 1994).

3. Dogs won't be happy after they're altered.

Dogs are not like humans. They don't look forward to having children, they don't expect to raise children and worry over them for 18 years or so, they don't dream of being grandparents some day. Male dogs don't even realize that pups they produce are their own offspring. A dog's reproductive urges are based solely on its hormones. Once the hormones are removed, the urges go away and the dog doesn't miss them.

4. A bitch will become aggressive after being spayed.

This is rarely true. As mentioned above under "points against sterilization", a bitch which is ALREADY aggressive may become more aggressive after being spayed. But the vast majority of dogs -- those who are NOT already aggressive -- will not become aggressive simply because they have been altered.

5. Dogs who are sterilized when young will be less stable and tend to have more behavioral problems than dogs who are left intact.

There is no substantial evidence to support this myth. Dogs who are altered early in life may sometimes be more active than their intact counterparts, but it appears that there is no other significant behavioral difference between dogs neutered very young (7 weeks) and those neutered later (7 months) (Salmeri 1991a). However, it has been well known for many years that altering dogs actually helps to decrease several significant behavioral problems, as mentioned above under "points for sterilization".

Also, consider this: Service dogs, such as seeing-eye dogs, are almost always altered before being put into service. Many dogs participating in advanced obedience competitions are also sterilized. Obviously, dogs must be very mature and stable in order to fill these jobs, and the surgery is performed because it actually INCREASES their stability by removing the distractions of the sexual cycles.

6. Behavior problems can be prevented by good training and socialization, so sterilization isn't necessary.

Good training and socialization are definitely essential to having a healthy happy companion. However, even the best-trained dogs in the world can have behavior problems. Remember, the sex hormones act on behavior at a very fundamental level, so those effects may override even the best training. Because of the effects of sex hormones, especially testosterone, intact male dogs are at the highest risk of any dogs for developing aggression problems (Beaver 1983, Blackshaw 1991, Galac 1997, Line 1986, etc ).

7. If I castrate my male dog he won't protect me any more.

Castrated dogs may actually be more protective, because they will no longer be distracted by the temptations of breeding. Instead of roaming after dogs in heat, or fighting with other males, he will be paying attention to you and you alone. In fact, one recent study has found that castration has NO effect on aggression towards unfamiliar people (Neilson 1997).

8. Only the dominant wolves in a pack get to mate, so intact dogs in a household won't be frustrated if they don't get to mate.

What do adolescent wolves do? They either leave the pack, start a pack of their own, challenge the dominant pack members for dominance, or help the parents to raise their future siblings. Do we want our pets to leave or to challenge us? Are we going to breed more puppies just so our intact dogs can have relatives to help raise? No. We want our pet dogs to enjoy living with us, not try to establish dominance over us.

Also, remember that our domestic dogs ARE NOT WOLVES. They act very differently than wolves do in many important ways, so we can't count on wolves to tell us how our dogs will behave.

9. My dog would make really great puppies/I want to have another dog just like my dog, so I'm going to breed him/her.

Roughly 25-30% of all dogs in shelters are purebreds. Even if your dog is AKC registered, that doesn't mean that the dog should be bred. Before ANY dog is bred the owner should prove that the dog will actually improve the breed. Thorough health testing, including tests for genetic diseases, should also be performed.

Also, your dog is a unique individual. There is no guarantee that puppies will resemble their parents in looks or personality, especially if the parents are mixed breed dogs.

10. Breeding dogs is a good way to make money.

The only people who make any money from breeding dogs are those who don't care about the health of their dogs or the quality of the puppies they produce. Responsible breeding requires health testing and medical care, as well as careful consideration of the pedigrees of the parents, their temperament, and whether their puppies would actually improve their breed or merely be more fodder for the shelters.

Medical costs before breeding will include extensive health testing, which may include xrays, blood work, tests for infectious diseases like brucellosis, tests for genetic diseases like von Willebrands, ultrasound exams to check for heart problems, CERF and BAER exams to check for eye and ear problems, and other additional tests depending on the breed of the dog. Medical costs after breeding will include pregnancy tests, ultrasound to check the progress of puppies, perhaps caesarian section if the dog has trouble giving birth, vaccinations, worming, tail docking and ear cropping in cropped or docked breeds, and veterinary care if the puppies should become ill. And that doesn't even consider stud fees, registration fees, travel costs to get to a stud, expenses to show your dog and prove that it's worthy of breeding, or the time you must invest in the mating, pregnancy care, whelping, feeding and cleaning the puppies, visits to the veterinary hospital, or advertising and selling the puppies.

11. My children should see the miracle of birth.

First, dogs usually give birth in the middle of the night when the children aren't going to be around, and dogs prefer to have quiet and privacy during birth. If the mother dog is disturbed by children or too many other witnesses, she may become stressed and abandon the puppies or even kill them. And, of course, there are already too many puppies dying in shelters every day.

Second, if you want your children to learn responsibility through caring for a puppy, there are many great puppies waiting for adoption at your local shelter. If you want to see the miracle of birth, you should first witness the miracle of death by volunteering at your local shelter for a few weeks. And there's a better alternative: if you want to witness the miracle of birth, rent a video.

12. We can find good homes for the puppies.

For every puppy you breed and place in a new home, a puppy or dog in a shelter may die because it wasn't adopted. There simply aren't enough homes for them all. And even if we ignore the puppies in the shelters -- are you SURE your puppies are going to good homes? Are you following them in their new homes throughout their lives? Are you willing to take the puppies back if their new homes don't work out? If you produce a puppy, you are responsible for it throughout its entire life.

13. We should leave our dogs as Nature intended them.

There is nothing "natural" about today's domesticated dogs. They have been created by many generations of human breeding. We have brought pet dogs into our homes, and we are responsible for their well-being. Dogs benefit in many ways from being sterilized, and suffer few serious consequences.

são felicíssimos. soube de um que morreu atropelado porque andava à solta. mas afinal, foi ele que procurou a morte.
outro foi deixado acorrentado até morrer. tb. vi um no vet. tinha a febre da carraça. a dona ao sacudi-lo as carraças caíam aos montes no chão. morreu nessa noite. o max tb. vinha bem. estava plantado na estrada. pesava 2 kgs e nem se conseguia levantar de fraco. as orelhas e cauda foram cortadas à tesourada. vinha com tinha e sarna. hoje, ao fim de 9 anos, é ainda um cão um pouco desconfiado e medroso. a dora andava atarantada na estrada. ao fim de 5 anos, não se aproxima de ninguém. and so on. e viva a demagogia e cegueira

[ziggy]

Com cães de raças grandes ou gigantes há o problema do osteosarcoma. Aconselhar os donos destes cães a esterilizar antes do crescimento estar terminado é irresponsável, visto que os benefícios não compensam os riscos. É muito mais fácil detectar e tratar um carcinoma da mama ou do testículo do que um osteosarcoma, portanto os benefícios da esterilização não devem ser generalizados a todos os cães.
