The next patient was a girl who looked like she could be in college carrying 3 large coolers with her. "Are you all set Jenna? Remember, once we do this, there is no undoing it easily. So make sure you are absolutely certain" cautions Dr. Vergunstien as she walks over to the girl. The girl, Jenna, is understandably taken aback at the sight of the 10 foot tall massive cock and balls version of the doctor she saw back a few months earlier.
"Oh, I had a special circumstance which let me gain some new features. This is Lilith and Maria, they cannot speak, but they can hear, feel, see and make small movements. I think they turned out rather well for my first attempt at turning human girls into testicles. Now then, let's step into the OR if you are ready."
Jenna nodded and picked up her 3 coolers and followed Dr. Vergunstien into the OR. Once inside, Dr. Vergunstien locked the doors behind them, and took the coolers from Jenna before telling her to strip and hop onto the table. After laying out the coolers, Dr. Vergunstien opened each of them to look at what she would be working with quickly before resealing them. Lilith and Maria got a quick glimpse as well and saw one cooler had what looked like the legs of a dog, the second had the entire back half and tail, and the small third cooler had the head. In other words, the mouth, nose, tongue, ears, and neck of likely the same dog.
"Is this everything?"
"No, I also would like to have 3 more rows of human breasts instead of dog teats. But aside from than that, then yes. That should be everything, although the reproductive system is still inside the body... sorry." Answered Jenna.
"No worries. I would rather do it myself than risk someone who has no idea doing it. I take it the dog was healthy when it passed? Work is still work, but I don't like it when clients go out of their way to kill for their parts you know."
"Oh yes, the dog was hit by a car. The chest area was what took the impact. We couldn't save it unfortunately." Said Jenna.
"That is why I never wanted to be a vet. Unlike you, I get really upset and depressed when I can't do something about a patient's condition. Perhaps that is why I am in to custom modifications and not life saving." Admitted Dr. Vergunstien.
Jenna nodded and laid back on the table. "So Jenna, who is the lucky family, or should I just let you go somewhere out on the streets as a stray?"
"I honestly do not care. I want it to be a surprise actually."
"Understood, then whatever happens happens correct? And I have received the payment so we are good to go when you are ready to begin."
"That is right, whatever happens, happens. I won't hold it against you or regret it later. Let's being please." Says Jenna.
Dr. Vergunstien injects her with anesthetics and hooks her up to the required life support systems. Lilith and Maria both watch in awe as Dr. Vergunstien expertly removes Jenna's various parts, and replaces them with their corresponding dog parts. Thanks to the numerous tools and devices, as well as her skills and a special substance she uses, Jenna is quickly combined with the supplied dog parts. Dr. Vergunstien lastly walks over to her great walk in cold storage and retrieves 6 breasts, each of matching size and pigmentation, in under a minute. Lilith and Maria do not appreciate the sudden extremely cold air and are huddled together and were even retracted upwards slightly, just like real testicles would be. "Sorry girls, but I can't help that it is cold for a minute. You will warm back up soon enough though."
Dr. Vergunstien spends a few more hours hooking everything back up and making sure Jenna's body is fully functioning. The last thing she does is combine part of Jenna's brain with the dog's. Specifically the parts where the dog's body movement, smell, reproductive instincts, and general mannerisms are kept and controlled by, is what she took to use in Jenna. She used them to replaced their respective parts of her human brain. This is what would allow Jenna to be able to innately understand how to be a dog from the get go, without having to struggle to learn every last detail.
The speed alone at which Dr. Vergunstien worked was incredible. And yet it took her less than 2 days to fully complete the operation. Now all that remained was for Jenna to heal back up, and she would be able to begin living the rest of her life as a human/dog hybrid.
Dr. Vergunstien though long and hard about what to do with her. And in the end, decided to just keep the new bitch for herself. She could use a loyal pet and this way she could keep an eye on her too. Plus, she does need something/someone to fuck now that she has two huge testicles that are always ready and willing to go at a moment's notice. So as a bonus modification, Dr. Vergunstien coated Jenna's dog pussy in a special solution that would make it extremely stretchy and able to be widened significantly without any pain or discomfort, but at the same time, able to retain it's current size and shape when not in use.
Thanks to her special solution, Jenna would be healed to at least the point where she could even wake up by as early as tomorrow morning. Now all that was left to do was to get some dog equipment like a collar, leash, food and water bowls, toys, etc...; and of course some dog food too.
