Favourite Dog in Bollywood Movie?

Who amongst these is your favourite dog in movies?

1) Entertainment from Entertainment movie 2) Tuffy from Hum Apke Hai Kaun 3) Charlie from 777 Charlie (i know not bollywood, but this had a proper Hindi release too) 4) Bhidu from Chillar Party 5) Moti from Teri Meherbaniyan 6) Rocky from Holiday

I was watching Chillar Party and realised its such a beautiful movie on a different subject, not regular run of the mill. Animals have played important roles in all these and manybother movies. Which one is your personal favourite and why?
