They would take the characteristics of the other. A dog would act like a human-being provided that they were raised around human-beings and the human-being would act like the dog.

The dog would find himself wondering why he was being punished so.

the dog would have to do the work for the person and the person would just play and have fun. I want to be a dog!

You'd have a dead dog and a dead human on your hands. Better cover that experiment up before it goes public!

The human would sniff the dogs butt, the dog would do its very best to use a loo, but fail miserably, with it's lack of aposable thumbs

I just bought the movie "Shaggy Dog" don't spoil it for me!!

Isnt that what happened to Ted Kennedy?

If it were a man and dog, you probably wouldn't notice anything different.

PHYSICALLY (assuming it was successful): There would be a lot of empty space in the person's head. There would either be an articifical skull attached to the dog's head or brains sticking out the stitch-seams (I prefer the former). MENTALLY: The person would be a complete dunderhead. The dog would be an absolute genius. EMOTIONALLY: The person would be very happy all the time, never self-conscious, and content to lie down and chew a tennis ball. The dog would be very sad and confused, and possibly traumatized. SOCIALLY: The person would soon lose all friends as a result of butt-sniffing, crotch-nosing, and face-licking. He would also drink from toilets and urinals and would soon lose his job. In addition, he would be naked, as dogs do not understand the concept of clothing. The dog would try to use the john. This would be unsuccessful for a time, and he will have fallen in more than once, preferably before unloading. The dog would also find himself completely helpless as he tried to dress himself. He would also be helpless in paying bills, and thus everything would soon be shut off. If, however, they ever managed to switch back, the poor person would have to get the taste of toilet water out of his mouth and deal with everything that the dog screwed up. Hope you liked it! I did! (No political comments, please.)

The man would snap his back trying to lick his ass and the dog would commit suicide for the agony of having a tail.

you'd start barking jingle bell while playing piano, hell i don't know.

they would be wondering what the heck is happing in this world, the human would be licking themselves in public and the dogs would be reading newspapers and going to work.

gotta try this on my neighbor, it would be a gas to see him get busted for humping the mailman's leg

The human would bark and the dog would talk?

the human would probably be smater and more loyal!! LOL :)

In my case, not too much.

Bill Clinton

Ruff, Ruff, Ruff....

My dog would steal my gf. That would suck. HOWEVER, I could easily lick myself to get over the pain.

Depends on the human, depends on the dog. It's possible you wouldn't notice the difference.

On my post delivery i'd knock at the door with a packet and if it was a nice blonde I'd start humping her leg.

I would be barking and looking for food all day long and Darcy will be scolding me and telling me to lay down.

Sheer entertainment.

A lot of ruff times...Doggone it...

I'd probably want to lick my genitals and my dog would probably want to have me fixed.

nothing a dog wouldn't be able to talk anyhow because they don't have the facial muscles to be able to move their mouth and the human...no difference there
