The moment he clicked OK for confirmation of his selection, Mike expected to feel an immediate change. Although the transformation began slowly, he didn't have to wait long. Already nude, he felt an itchy feeling spread over his skin, a change that signaled the sprouting of dark hair on his arms, legs, and other areas. He already had Jake's genitalia, so the program skipped that sequence and more rapidly began to change Mike's skeleton and musculature. For instance, his skull widened and flattened as strong facial muscles attached his strong jaws to the rest of his heavy skull.
"This is fantastic," he said, his throat grating as he produced the words in a more gravelly voice than usual.
His bipedal stance began to feel wrong. Getting onto all fours not only felt natural, it felt more comfortable, as well. The spread of dark fur over his entire body continued at a pace.
He wanted to witness Jake's own transformation, too. "Ja-hake!" Mike growled in a husky voice. "Boy, come here! This is incredible!"
In response, Jake barked and trotted across the room on all fours.
Mike looked at his dog. "Why arrr-ant you chaa-ngeing..." Mike growled as his throat muscles rebelled against his attempts at human speech.
If his master's unexpected acquisition of doggie privates had caused Jake some confusion and upset, it was nothing like finding a strange dog suddenly intruding into the living space he shared with his master. Jake barked again and began growling as he advanced on Mike, who realized something hadn't gone according to plan.
He barked in excitement and felt a shock at discovering he had lost the capacity for human speech. His mind still hurled words at him to say, but when he tried to speak he produced only a discordant mixture of barks, woofs, and yelps.
"Why aren't you changing?" Mike wondered as he looked at Jake with placid eyes set above a blunt snout and evident jowls.
He hurried across the floor, not yet fully adjusted to four-legged locomotion. He had left the device on the kitchen table, so he launched his forelimbs onto the edge of the table and supported himself on wobbly hind legs.
"What happened?" Mike barked as he scanned the settings.
"No!" Mike produced a loud woof. He saw that he had failed to nudge a check into a box to confirm Jake's change into human form. One stupid mistake — a failure to click one little box — had botched the entire scheme.
"Maybe I can still click it," he whined and cringed as he tried to lift a paw over the device. With a design very much like the touch screen of a smartphone, the device was simply not designed with canine form and capacity in mind. Mike realized the futility of his effort.
He realized that the entire plan had been predicated on Jake's ability to change them back into their respective forms.
"Fuck!" He barked. "Am I stuck?"
In the meantime, poor Jake tolerated the intrusion, but a furious debate took place in his simpler brain. Should he defend his home turf from this interloper. A lingering scent that reminded him of his master stayed him, for the moment. Then the other dog jumped onto the table, which was something that Jake had been taught was very wrong. It was outrageous behavior from his point of view.
With a growl, he surprised himself and Mike by hurling himself onto the other dog. In a tangle of eight legs, both dogs fell in a dark-furred heap on the floor. Jake, perfectly at home in his canine body, held a definitive advantage over poor Mike, who still had a lot to learn about being a dog.
In seconds, he had a whimpering Mike on the run. The defeated and suddenly submissive Mike locked his eyes on the doggie door that he himself had placed in the kitchen door to permit Jake free exit and entry into the house.
