I have 2 yorkie's boy and a girl.

My girl is very tiny probably (rough guess) 3lbs and my boy is standard size if not a little larger maybe.

Boy is 2 yrs 9mths and my girl is 1 next week.

Hollie is in 2nd season and having not had either one neutered yet i have been keeping them apart for last couple of weeks.

This was until my mother in law came over a couple of days ago, let herself in whilst we were at work, let dogs out unknowingly and left them in kitchen together for rest of afternoon.
I came home to find both dogs together, hollie is so small she can fit in a gap between fridge and work kitchen units and was hiding out there. As you can imagine i was so cross as i religiously kept them apart to avoid risk of her becoming pregnant but she did it by accident without knowing that they needed to be kept apart and why.

I am extremely concerned about the risks this would pose to her should she become pregnant because she is so small.

Does anyone have any advice?
