Will a trained guard dog choose loyalty or call of the nature?

Suppose that a male dog named “Max” has been professionally trained by his owner to attack any creature that step foot in the yard, except the owner himself. Max has proven this for a long time as he keeps on attacking any creature that got in to the yard without fail. Max is an intact male, and one challenge that has never presented itself to Max is the presence of an Intact female dog.

Suppose there’s a female dog that has been trained professionally by her owner to lure male dog in to bushes where a trap has been set. She will always do her mission while she’s in heat. Let’s just call her “Lola”. Lola will approach a male dog, let him come closer for a sniff, and before he can mount her she’ll move (with owner’s instruction if needed) to a different spot as close to the designated bushes as possible and repeat the tactic until the target is finally captured in the bushes. Finally, today her target is “Max”, notorious for his aggressivenes and attacks, despite that, Lola still match on the yard, her owner believe that even a trained intact male dog cannot resist the call of the nature. Max and Lola are about the same size. Lola step her paws in to yard, ready for her mission…

What would most likely happen to them? Can she lure him out of the yard and in to the bushes? Or will he able to resist the call of nature and attack her regardless? Will Mother Nature’s design always overwrite a dog’s loyalty to his owner? Who would you bet your money on?
