After beginning estrus in early August, Piggy bled for almost a month. Now her nipples are engorged. She was never near un-neutered male dogs but I did take her to a dog-sitter for a weekend and she told me the same information. I am starting to wonder if the dog-sitter, who came highly recommended, has lied to me. How significant will the nipples swell with a hysterical pregnancy? Will the abdomen become tighter? The visit with the sitter was a month ago, if she was impregnated, when would I be able to feel fetuses? She does not seem to be acting any different. Anyone have any thoughts on real pregnancy vs. false pregnancy? I think I am just being paranoid but I am starting to wonder if I should start feeding her more just in case….
