Infertility/Sterile question

So recently my mom told me that a member of her family told her that she knew someone who couldn’t have babies due to the fact that she slept with her dog. She said that she went to the doctors and they said it was because of that. Now I didn’t believe a word she said and called BS, but my husband and I do sleep with our dog and I can’t help but wonder. I know it sounds ridiculous but sometimes you just look for a reason. We’ve been having unprotected sex for a year and a half and I know there could be many factors I’m just curious about all your opinions! Help!

UPDATE: I apologize everyone, I assumed it was obvious that what I meant is that our dog sleeps in our bed with us. I’m not some freak, our dog is like our baby.
