In humans, we don’t usually castrate them because it throws their hormones out of whack, and causes all kinds of issues, but wouldn’t that also be the case for some animals, since their hormones systems are fairly similar?
Why is it that that we remove the testicles entirely, rather than giving them vasectomies like we do for humans?
Your knowledge of neutered dogs who do not follow the desired behavior pattern is really cool! I have some knowledge about neutered dogs who did experience the expected and desired changes in behavior. Cool!
