I am afraid that the same problems would exist with the dogs that belong to these sort of owners, even if the dogs were castrated.

Castration CAN reduce certain types of aggression in certain dogs.......

I guess you and I must have different experiences then, because never once has it been a neutered male following us, licking my dogs bits, posturing, salivating and trying to mount, with it's head inserted up my dogs bum! I avoid the entire dogs that I know of like the plague, as do others.

There is someone in my area who is very into his working gun dogs, they are all entire, they all behave about as impeccably as you can have a dog behave. These dogs are very well trained, polite and sociablly sensible dogs. Try telling him to go and neuter his dogs to improve their behaviour! Just one example. He himself has commmented on neutered/spayed dogs causing confusion in entire dogs and also not always reacting reliably etc and Iv seen it too. However I do not accuse only neutered dogs of causing problems on walks etc. (neither does the person I mentioned) Most of the dogs that act aggressivley towards mine turn out to be neutered males, again, I dont go blaming DA on neutered males.

My boy has his and Ive never felt the need to chop them off.

he doesnt like another dog putting its head over his shoulder and if an entire dog approaches him and is 'rude' he will be most verbal about it but he doesnt go 'looking' for trouble.

Highly submissive/nervy dogs make him suspicious and are viewed with caution

He has been disliked by any collie we have ever met and one in particular liked to grab his face when its owner wasnt concentrating. which he ignored point blank as he does when anyone smaller than him lunges at him with the spikey end flashing

Big black dogs he has never liked.

He has a girlfriend who he will have a cheeky hump of now and again if Im some distance away but a sharp 'leave' will put a stop to it. we went to my friends one day and he completely ignored their JRT who was in full season (she forgot to let me know!) who kept throwing herself at him in favour of going and playing with said gfriend.

hes never humped or marked in the house (ok he humped a guys leg once after going to greet a whole room of people at xmas he went all the way round the room kissing and smiling until he came to a particular chap who he took one look at and humped his leg!! - funnily the chap was known for being a bit of a wet wendy and being hen pecked by his wife. he only ever did it that once)

he prefers a good wrestle i think

i often wonder if entire dogs are physically more robust than others (reproductive organs aside) does neutering have an adverse effect on them physiologically/structurally? - i seem to read more and more these days dogs suffereing things like cruciate issues etc and it makes me wonder. If i was a scientific researcher I would investigate

Your not the lovely lady with a dobermann who I met in a wood in Northamptonshire the other day are you? You sound as nice as she was!! Her dog was absolutely fabulous! .

Interesting point you raise about neutering having an adverse effect - I have no idea whether it does - I know it frequently will cause weight gain unless you watch the food intake. The metabolic rate reduces with castration at the same time as the appetite increasing slightly, with the inevitable weight gain unless steps are taken.
