A female pug tends to prefer a male than another female
A male can smell a female pug in estress for 5 miles. The animal kingdom is based on reproduction. It is best to get the female spade and the male fixed. The male pug will NEVER calm down while the female is in estress
It is simply a bad dog behavior.
separate them other wise you can't it's biology
Yes, as long as the chihuahua is "in heat" and they get "hung" (which you will know), the pug can get the chihuahua pregnant.

You need to separate the dog from the bitch and only bring them together under controlled circumstances. Pugs often cannot mate unassisted. If you are not familiar with pug breeding what are you doing? Do you have any idea how hard it is to breed and whelp Pugs, females regularly need caesarian section, cannot give birth unaided and do not care for their pups. Unless you are very experienced I really do not recommend you breed your pug.
