I can tell you just from comparing two dogs one who was spayed before their just heat and one who was not by flipping them on there back with out any studies you can see that the mammarys are developed in the non spayed before first heat female and they are not in the female that was fixed before her first heat. With no developed mammarys there is a much less of a chance of mammary cancer. I have heard and seen many cases of mammary cancer. Of course every one needs to read and do there own research but upon doing mine it is simply a personal choice there is no science to back up that waiting is best. The growth plates still close and so on after being spayed. Although I do not recommend spaying before 6 months the younger they are the faster they heal and recover. I personaly have not seen anything that would make me sway from getting them fixed before there first heat.
