To the first person who answered the question - what if the questioner was wondering if something that they did made their dog have a miscarraige? You shouldn't just jump to conclusions like that...
Why would you even want to do that?
Yes but that would be very wicked, it best to make her have the pups then spay her.
Maybe but that is really sick and you don't deserve to have a dog if that is what you want to do
