My Dog Is Pregnant For The First Time I Know That A Dog's Gestation Period Is For About63 Days, But I Am Beginning To Think That She May Be Further Along Than The Vet Suggested. I Know That She Went Into Heat Sometime In Oct. But I Don't Know When. What Are Some Of The Signs Week By Week That Might Help Me? Just so you know we did not plan on her getting pregnant. We kept her in the back yard while she was in heat and another dog dug a hole and came on in. As soon as I realized that she was pregnant I began to find homes for the puppies immediately. Luckly I have eight familes lined up so I know that the puppies will be well taken care of. I also have Blue scheduled to be fixed as soon as she has weened the pups.
