I have a English Springer Spaniel that was bred by a yellow lab that was passing through the neighborhood last night. How do I get the morning after pill or injection for her so that she does not have puppies? This dog was a lot bigger than my dog. This is also her first time of mating. It is her 2nd time of coming in heat. Today is her 11th day and she is still bleeding. Do you think that the mating took? The male dog was locked onto her and my dog was crying as if she was in pain. Please help me.
