Katie hugged her and ran her hands through her hair, "I'm so sorry Tiff, now we need to find a way to help you too."
The way Katie was petting her made her wag her tail so hard that the whole rear part of her dog body shook. She wished that Katie could keep it up all day, or maybe rub her belly some, "If you want to help me you can give me a belly rub when we fix you up. That would be nice, and then go out any play with me."
She snuggled up against Katie and tried to hug her and lick her face again, but Katie took a step back, "That's enough Tiff."
Tiff hung her head and tucked her tail between her legs, "Sorry."
"That's alright Tiff, just don't lick me anymore. It's pretty disgusting."
This made Tiff whimper, but Katie had already turned away to look through the refrigerator to see if there was anything she had missed. Determined to help, Tiff began to sniff around in the kitchen to find something that might be useful. The problem was that there were so many interesting smells that she quickly became distracted. Figuring that Katie wouldn't be mad if she had a snack while she searched Tiff went back to the cabinet where she first found the dog treats. There were so many yummy smelling snacks that she didn't know where to begin until she saw a pack of two large chew bones. They smelled so delicious that she just had to have one. First she checked the label, because she was smart enough not to try something without seeing what it was first. They sounded harmless enough, 'Vitamin enriched chews for strong dogs' so she took one out and began to gnaw on it as she looked.
Muscle flowed over her already fit frame until her pit bull body became the very image of what was feared of the breed, and the muscle growth spread to her human body as well. She didn't become overly bulky, but all of her muscles were lean and clearly defined. The change was hardly worth noticing as far as she was concerned because in another cabinet, this one over the sink she found something rather promising.
Rearing up on her hind paws to get a look at the top shelf she reached up with her arms and removed the box that had first caught her attention due to its funny smell. Still chewing on the bone she read what the contents of the box were supposed to do, 'For increasing female fertility and preparing for conception'. As far as Tiff was able to tell it would work to bring Katie out of her false pregnancy since being pregnant meant that she wouldn't be able to get pregnant again at the same time. A find like this would make Katie happy, Tiff was sure of it.
Taking the bone out of her mouth so that she could speak she called out happily, "Katie, I found a way to make you better again!"
Something about her voice struck her as odd, but she wasn't quite sure what. It made her let out a small, puzzled grumble as she tried to figure out what was wrong with her.
Katie turned to look, but her eyes focused on Tiff rather than the box she was holding, "Tiff, what did you eat?"
Puzzled Tiff looked at the bone she was holding and then back to Katie, "A vitamin enriched chew bone for strong dogs. At least that's what the label said I think. Why?"
Again her voice sounded strange, deeper maybe.
"I think they meant for male dogs, or else they would have said for bitches," Katie winced, "I didn't want to call you a bitch, but look at yourself."
Tiff did as told and saw that her breasts were gone, replaced by well developed muscle. The meaning of what Katie was telling her began to sink in. Craning her neck and looking back she was able to see a furry sheath running along her belly. The chew bone had made her a male dog, that explained why her voice was deeper. It didn't bother her too much though since she figured that the stuff in the box would also work to make her female again, "Don't worry, this stuff will make everything all better!"
She handed the box to Katie and wagged her tail as her friend read what it did.
