I was taking my dogs out to the bathroom in my backyard and previous that morning she got out an i didn't know. So later that night like at 8:00 pm i went back outside to take the dogs to the bathroom and i seen her creeping back on to the porch. She is 9 months old and when she came back in the house she looked a little larger and she had lumps in her stomach and now her nipples are becoming visible also she doesn't really like me touching her belly is she pregnant.
