"Very well then", says Madame Illusia, "you shall be his mate." She snaps her fingers and just like before, the man seems to be trembling in shock with a hollow stare in his eyes as fine white hairs begin to sprout all over his skin, soon growing to a length that covers his entire body. Over the layer of fine white fluff grows a second layer of rougher light grey hairs, although most of his front stays white. His fingernails blacken and become pointier, completely integrating with his disappearing fingers with his hands and feet now being little more than clawed stumps without opposable thumbs. With a loud clicking, the bones in his legs shift around to support a completely quadrupedal position, after which he falls over forward and lands on his forepaws with a loud thump.
The changes to his face have already started with his lips shrinking and his nose gaining a wet, black leathery texture. His jaw can be quickly seen expanding into a muzzle, and as he opens his mouth to moan the public can get a good view of his teeth changing, ones suitable for a more carnivorous diet. At the same time his tongue can be seen changing, flattening and stretching out, ultimately hanging out of his mouth flicking back and forth by which time the final part of his mouth has definitely changed as the moan has turned into a silent "grrrrr...". His eyes quickly gain a deep tint of yellow, the pupils changing to canine eyes and his ears moving to the top of his head.
With a loud cracking, his neck practically disappears, his spine straightening out as a bulge starts forming in his pants, growing and growing...until finally a large bushy dog tail happily flops out, swishing all the way. "You'd think we're done with this", Madame Illusia says looking at the still fully clothed dog who now just sits there with his tail swishing and his tongue hanging out of his mouth, "but as you have agreed to be his mate, you can impossibly be male. That is why we'll fix this now, and remove your clothes for all to see." She clicks her fingers again, the man's clothes vanishing in the same black smoke as before, leaving a grey furred dog with his manhood visible. "Now, observe!"
He cringes as he suddenly feels something shifting around in his new bowels - his innards had been changing all the time, but now it really feels like a new organ is forming inside - inflating his underbelly a bit as his sheath starts getting smaller along with its contents. Quickly, his entire penis seems to be sucked into his crotch, even completely inverting until none of it is visible anymore, his scrotum getting sucked in along with it. A hole is now where his manhood just was as it slowly shifts into position, just below the anus. Finally, a tingling in the chest can be felt as six small teats rise up as bumps in the fur, the new bitch completely surprised at all the new feelings as she bends her head to her chest to look at all the new stuff.
"There we have it, ladies and gentlemen. This brave girl will from now on gladly bear the children that her mate here will bring forth." The audience gasps and claps in shock and amazement as the two Alaskan canines have already started taking an interest in each other...
