Ok It has been a few days since I found that black dog in my yard with my boxer ( who isn't fixed yet). She has an appointment on Thursday to get spayed. Would it be too soon to tell if she's pregnant? I have looked for that other dog and can't find him anywhere so I don't know if he was fixed or not. I was noticing today that August's nipples look larger. I can't afford to take her to the vet for another two weeks. Is there anyone who has ever had a pregnant boxer that can help me? This dog was a little bit bigger then August but I don't even no if he mounted her. I really could use some edvice. Thanks. Norma.
