I am a Veterinarian as well. I agree with what Dr. A said re early spay/neuter. There are theories that doing it early (<3-4 months) may predispose them to ligament or tendon problem, but there is no real evidence of it. They do tend to have a little higher incidence of urinary incontinence, though.
I have not seen any sex differences re cruciate tears, though. I find I'm fixing male and female cruciate tears with about equal frequency. They are almost always overweight dogs, and Labs are overrepresented.
We recommend spay/neuter at 5-6 months of age.
