Well how do I start this

Well you all know Bon a male (duh) and at some point we do intend on getting him neutured. But the question now is...When?

I know alot of you would say now, but before you say first that tell me how much you know about Giant breed dogs. I have done alot of research on this subject and keep coming back to the same conclusion. Almost every website that I have visisted says to wait till at least 2 years on neutering the giant breed males...this is the reason they all give
With large breeds, early castration often results in an animal with an insufficient breadth of chest for orthopedic health. Seeing the number of giant breeds that I do, I am very aware of the tragic effects of castration on young males. The narrow chests which result are inadequate to support the weight that so many neutered animals, male or female, put on. These dogs then have to develop a 'toe-out' stance, with valgus deformity of the carpus, in an attempt to broaden their base for weight bearing. Once you've seen the harm caused by this practice in person, you quickly change that 'knee-jerk' reaction so often seen, of 'neuter everything that breathes'. If you do choose to castrate your male dog, by all means wait until he is at least one year old for small to medium size breeds, or at least 2 years old for giant breeds.
The reason I'm asking is because we are planning on taking a vacation without the dogs in August and I want to board the dogs at a really nice place, but there is one stipulation...all males must be neutured. Well in August Bon will only be 1 yr 1 mo.
Now if I had somone who could keep him and I could board the girls that would be great, but I really don't know anyone who is going to be willing to keep a 150+dog for us!

So I just feel at a loss right now. I want to do what is best for our boy.

Any help would be greatly appreciated!
