No.
It is impossible to get pets in Animal Crossing, if that is what you mean. However, you can buy a dog house in Tom Nook's store, but this won't give you an actual pet.
Animal Crossing Cityfolk is the latest out of the two. you do realise you can check wikipedia for these?
No. Why would you want a dog in animal crossing, when there's animals all around? Free loader....
No. Same apply to all Animal Crossing games and Pets outside of the house and cage (tank).
I don't think there is a way to get a dog unless they made an action replay code for it.
Via DLC (downloadable content) yes
