Miss mating

Jilly my chocolate Labrador came into season. I hadn't noticed but Oscar had. He told Buster, my partners castrated labradoodle, under no uncertain terms to stay away from her. I thought this strange as Oscar is such a laid back, cool dog. I made sure Buster was ok, turned around to see Oscar and Jilly tied (mated). Oh! No! As she was to miss a season, off to our vets we went for the "morning after" type injection. 

She seems fine and suffering no side effects and the resulting puppies should be reabsorbed.
