What is nintendo dog?

You're thinking of Nintendogs for the Nintendo DS. I've never actually played it, but it got pretty good reviews, actually. I guess if you don't already have a dog and have time to play the same video game every day, you might want to look into it.

have you ever seen that small handheld game that came out about a decade ago which was about taking care of the animated cat or dog... you had to feed them, bathe them etc. at various time in the day (or night as well maybe, not sure cause i haven't played it). and if you are careless, the cat/dog will die and your game will work no more (that's what i heard atleast). nintendogs is a similar game where you have to create and take care of your dog and train it as well. i don't know much about the game cause the genre doesn't interest me.

I have it, and it is pretty fun (for a while). You train your own dog (puppy), teach it tricks, and then show off those tricks in different contests. The way it uses the DS's microphone is pretty nice too, and it's more accurate than you might think. You teach your dog (or dogs, I think you can have up to 6 :o) tricks by using the touch screen to shake their paw, or grab their tail, and then you have the opportunity to try to teach your dog that trick. It may take a few tries, but it is pretty fun. But it's a lot more fun if you have a friend with the game, that's probably the reason I don't place anymore.
