The Sound Of Settled Science

This large scale data collection involved 9938 dogs;

 In many countries, the vast majority of male dogs are castrated routinely to prevent the overpopulation which has crowded many shelters and forced them to euthanize countless numbers of dogs. However neutering male dogs has also become a routine suggestion of many veterinarians when their clients tell them that their dog has shown aggression—especially toward family members, or for a variety of large or active breeds. So this recent study sought to see if there were any behavioral benefits or problems associated with neutering, and to see if the age at which the dog was neutered made any difference. […]

 

As in previous studies, the new data clearly shows that the positive behavioral effects that were expected from neutering dogs did not occur, and if anything, the behaviors of neutered male dogs tended to be considerably less desirable. Of the 100 behaviors assessed 40 showed statistically significant differences between the castrated and intact dogs. Only four of these behaviors showed a more positive outcome as a result of neutering. Neutered dogs were less likely to urine mark indoors, or to howl when left alone. Neutered dogs, when off leash, were also more likely to return when called, and also tended to reliably fetch tossed items. That’s it for the positive effects of neutering. The other 36 behaviors were all more negative in neutered male dogs.

  1. So it turns out that turning your dog into a liberal does not improve his behavior? Shocking!

  2. The first reason mentioned is still the best reason to spay or neuter your pet. Puppies are cute I’d rather not return to the days where they were euthanized regularly because there were so many of them. Let the responsible breeders do their thing and let’s keep the shelters empty.

    1. Yeah … that would require responsible behavior, it is much easier to be a liberal and turn your dog into one too.

  3. if you’re going to euthanize you might as well turn it into a food source.

  4. Not surprising.
    Libs have been castrating, neutering, spaying, tying off, pilling, rain coating, us for years. look where it has gotten us. Kripes some people are even confused about what gender they are and ex-husbands hang around for more psyco-abusive B.S. than ever before. It’s insane, it’s b^lless.

    Anyone who has been around fertile male dogs knows they love their b^lls. Train and fence the animal appropriately. If he keeps getting out snip him. If the behavior continues the dog has to go one way or the other.
    And, by the bi, when bitches are in heat they need to be locked up. Estrogen causes all kinds of problems, especially when taken daily.

  5. I live with an outdoor tom that is now 10 years old … he is the first unneutered tom I’ve been close to and he is the most grounded, non neurotic cat I’ve known. In the city he sleeps out each and every night, he goes north with me to the cabin in summer – confidence camp I call it – and has been on his own for weeks at a time.
    The down side is that “Rocket” gets in fights and receives bites — love bites possibly — I treat the resulting infection with Polysporin. Neutered male cats I’ve known have also got in fights
    This male dog study isn’t a surprise to me …. neutering animals and people can make them neurotic, IMHO

  6. Funny. When human perverts are neutered, they uniformly describe it as the best thing that ever happened to them.

    Of course, that is rarely done any more, because we are obliged to embrace sexual abnormalities, not try to cure them no matter how cheaply and safely it can be done.

    Leave innocent dogs intact. Neuter perverts instead.

    1. In the era of Me Too drive-by character assassinations I’d be careful about giving the government power to neuter people.

  7. I have had several male dogs, some of which were neutered and some were not. I do not see any benefit to neutering other than it can decrease the risk of prostate cancer.
