Santé : Stérilisation du chien - Pourquoi, quand, comment ?

On le fait pour les chats, parfois même à 8 semaines (bon, ça je trouve trop tôt), mais les chats d'élevages sont souvent stérilisés à leurs trois mois.
Alors pourquoi pas pour les chiens?

Bon, j'ai remarqué que mes deux chats stérilisés à leurs 4 mois restent plus petits que les autres, mais ce sont des chatons biberonnés, qui ont été malades très longtemps, aussi, alors ça compte pas vraiment.

Je e suis faite la même réflexion que Fahn, la plupart des chats LOOF sont stérilisés avant la vente. Je chercherais l'influence que ça peut avoir sur la croissance mais je ne suis pas certaine que ça soit excessivement mauvais. Mais contrairement à ce que tu dis, les animaux stérilisés dans leur prime jeunesse devraient être de la même taille à plus grand, puisque ce sont les hormones sexuelles qui mettent un trait sur la croissance osseuses, mais du coup, je me demande s'il n'y a pas une augmentation du risque d'ostéosarcome...

Je ne sais pas, ils ont tous été stérilisés avant leur puberté, mais les plus jeunes avaient 4 mois. Coïncidence ou pas, ils ont eu bébés le typhus, le coryza, ont eu beaucoup de médocs et on été souvent malades par rapport aux autres, c'est peut-être plutôt ça qui a joué, ou leur morphologie qui est simplement faite ainsi.

C'est surement un combo maladie+ morphologie. Peut être aussi la stérilisation à un moment où ils étaient déjà faibles, et ça les a encore plus affaiblis.

"Early-age neutering

Early-age neutering (or prepubertal gonadectomy – the removal of the ovaries or testes before the onset of puberty) is typically performed in dogs and cats between 8 and 16 weeks of age, as compared to the conventional 6 to 8 months. It is used mainly in animal sheltering and rescue where puppies and kittens can be neutered before being adopted out, eliminating non-compliance with sterilisation agreement, which is typically above 40%.[2] The American Veterinary Medical Association, American Animal Hospital Association and the Canadian Veterinary Medical Association support the procedure for population control, provided that the veterinarian uses his/her best knowledge when making the decision about the age at neutering.[51][52][53]
While the age-unrelated risks and benefits cited above also apply to early-age neutering, various studies have indicated that the procedure is safe and not associated with increased mortality or serious health and behavioral problems when compared to conventional age neutering.[54][55][56][57][58] Anesthesia recovery in young animals is usually more rapid and there are fewer complications.[58][59] One study found that in female dogs there is an increasing risk of urinary incontinence the earlier the procedure is carried out; the study recommended that female dogs be spayed no earlier than 3 to 4 months of age.[55] A later study comparing female dogs spayed between 4 to 6 months and after 6 months showed no increased risk.[60]
One study showed the incidence of hip dysplasia increased to 6.7% for dogs neutered before 5.5 months compared to 4.7% for dogs neutered after 5.5 months, although the cases associated with early age neutering seems to be of a less severe form. There was no association between age of neutering and arthritis or long-bone fractures.[55] Another study showed no correlation between age of neutering and musculoskeletal problems.[57] A study of large breed dogs with cranial cruciate ligament rupture associated early-age neutering with the development of an excessive tibial plateau angle.[61] Female dogs neutered early are much more likely to develop cystitis although the risk does not appear to be chronic. Two studies showed an increased risk of canine parvovirus infection, which one of the study attributed to the increased susceptibility of young dogs rather than long term immune suppression.[55][57]
In terms of behavior in dogs, separation anxiety, aggression, escape behavior and inappropriate elimination are reduced while noise phobia and sexual behavior was increased. In males with aggression issues, earlier neutering may increase barking.[55] In cats, asthma, gingivitis, and hyperactivity were decreased, while shyness was increased. In male cats, occurrence of abscesses, aggression toward veterinarians, sexual behaviors, and urine spraying was decreased, while hiding was increased.[54]"

http://www.avma.org/avmacollections/obesity_dogs/javma_224_3_380.pdf ==> conclusion de cet article: "Because early age gonadectomy appears to offer more benefits than risks for male dogs, animal shelters can safely gonadectomize male dogs at a young age and veterinary practitioners should consider recommending routine gonadectomy for client-owned male dogs before the traditional age of 6 to 8 months. For female dogs, however, increased urinary incontinence suggests that delaying gonadectomy until at least 3 months of age may be beneficial"
