It was confirmed today after a week or two of suspicion that my chocolate female lab is pregnant, by hopefully my other chocolate lab. She is kept inside two gates, and has never been unsupervised around any other intact male other than Pete. Of course, this is all my fault because my husband says I don't watch her carefully enough when she is in heat. Tips for birthing puppies? My husband is building the whelping box as we speak. She's due in two weeks.
