first of all it can happen, my first male yorkie tried mating with a gsd female, he got on the sofa and she backed up to it
we were in the room so nothing happened but it just goes to show wheres theres a will theres a way
.
a friend of mine had a jack cross gsd.
the vet could tell in a couple of weeks if she was pregant, my vet could feel sasha (yorkie) was pregant after 2 weeks and that was by another yorkie.
sasha also started putting on weight within a couple of weeks so there are other ways of telling if shes pregant.
