Sorry, but I believe that dogs' health should come first. I understand the dilemma that it puts shelters and rescue agencies in, but in general I believe if you can't handle having intact dogs don't get them. Full stop.
The more research that is done the more clear it is that we hurt dogs by neutering them. Yes it is annoying to keep a bitch safe once or twice a year when it is in heat, but if you aren't willing to do that why would you get it? Nor should his health suffer because you chose to get a bitch and seem unsure of your ability to keep them separated. I really wish people asked this question before adding an intact dog to their family.
The next question is whether you are willing to keep them apart and want help with ideas on how to make it as peceful as possible. Having lived with a male dog that howled the entire time we had a bitch in heat, I can only say that it isn't Fun but it is doable. You can do this!
