My name is ***** ***** I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
Actually I have two male dogs myself and they are not neutered, they are almost always good boys.
But I think if they were presented with a bitch in heat that I would have problems as well. Very few male dogs would be able to resist that sort of temptation, that's just nature I guess ...
My own take on this is that if the dog is otherwise good and obedient I would not consider neutering, it will be a rare event for your dog to encounter a bitch in season so this will be a rare event
I hope I have covered your question fully enough but if you would like further clarification or to talk things over a bit more then I will be on-line for the next hour or so and I will be more than pleased to continue working with you.Regards,Scott
