You would absolutely have to keep them apart. I know some people send the boy out to live somewhere else for a month or so. Grandma's maybe, or a good friend.

This is a reading list of articles and papers by Veterinarians, breed clubs, trainers and others on the pros and cons of neutering or spaying your dog that I have found helpful and very educational. Most are based on extensive Veterinary research and also provide references you can check further. If you are wrestling with the question of when or whether to neuter/spay these may help. They do not all agree and one is even a rebuttal of another. One is a link to a radio show interview. One is a link to a medical testosterone suppressant not yet available in N. America but is in the U.K. and Australia. Some are not easy reading.

I think I personally found the first two in the list to be of most help and I appreciated the non-biased way the information was presented. The list is in no particular order, articles were simply added as I discovered them. If the links are not clickable I have tried to include the name of the paper and author in case you have to search for them. I hope this helps folks out and good luck with your decision. A tip, I went to my Vet to discuss the first two articles with her.
