Jen's parent had contacted the school and successfully pulled her out for the next 3 months on the excuse of going on an extended leave for an exchange program she took part in outside of school. Of course this was all a lie, and it was just to allow for her to brith her pups and nurse them uninterrupted.
When Jen's mother said that she would be considered just another dog to them, she wasn't embellishing anything. Jen's room was gutted and a large dog crate made for 2 dogs to share, had been put where her bed was. Several doors had doggy doors installed and her father had put up a tall fence closing in their back yard.
Jen's mother did in fact get Jen a collar, and she would never take it off, not that she could either. Jen's mother had even gone the extra mile and had purchased a few bondage items used for pet play for Jen to wear at all times. Specifically a pair of mittens that bound her hands into fists with pads on the underside, and a dog tail plug which matched her hair perfectly. Jen would not be able to remove it herself either and would require one of her owners, as they insisted that she now only think of them as being, to remove it whenever she had to go. Jen now exclusively ate and drank from her dog bowls, and her mother had even found a specially made "dog food" meant for humans to use durring long sessions of pet play. This quickly became her only source of food.
Jen was not fully aware of just how dog-like she had really become. Be it her 8 milk filled breasts with somewhat long teats lining her front or how she naturally panted with a much longer tongue when tired. Her tail plug had disappeared one day, and had been replaced by real tail, which no one seemed to notice either. One day she woke up and there it was, wagging happily back and fourth behind her.
Jen had all but stopped caring about being human. She loved being a bitch way to much to ever go back. As her due date approached closer and closer, she really started to take on the pregnant appearance too. She loved her owners very much and would happily greet them whenever they came home from work by licking their faces.
It had been about 2 months now since the time she got impregnated and she was due any moment now. She could feel all 8 of her pups inside her womb. Occasionally they would squirm or kick, which would be uncomfortable, but she was proud to be their mother nonetheless. Her boobs really were filled with milk now, and all 8 had now become around the same size, roughly C-cups, each topped with an inch and a half long teat. It was only a day and a half later that Jen finally gave birth to her first of many litters.
