I need a bit of confirmation here please……..whilst I know it may be a bit early, I’m going to try and get an idea… My dog has just come of her first heat, being a larger dog breed, she is a lot older than 6 months old. I think its been a bit over a week, if that, since her heat has finished. We do have a full male Pitbull x Red Heeler x another dog breed, but we tried our best to separate them, there was only one night where she was outside with him unsupervised during the time where she could breed…don’t know how long she was outside for, but the little rascal is smart. But other than that, she was separated from him, and when they were together, they were supervised at all times. We also have a desexed dog, but he couldn’t do any harm to her. Apart from being a pain in the butt during that time…….. I notice she now has very swollen nipples, and the area beneath the nipples are ‘devolving’ and are not flat like before her heat. The nipples by her hind legs are also getting hints of pink. (Im looking here for the early signs of dog pregnancy: https://sykesvillevetclinic.com/dog...ant-the-early-signs-and-what-to-do-if-she-is/ ) I sure hope she is not pregnant. But I think im wrong. I did a lot of research when she was little as to spay her or not, I found a lot of negatives to spaying, so I decided not to get her spayed.
