Update: My Dad took the pup from my friend. ACtually, my friend isn't really selling the pups - the mother was weak, pregnant, and abandoned when he found her. After being taken care of, the mother deliverd 5 pups.
My dad had fallen for the pup (or probably, the idea of a pup) and now he has hired a full-time (all-day) caretaker who my dad has known for a long time. The caretaker will feed and walk (5 min for now) the dog, and tend to some gardening and cleaning.
And my dad is going to be working only 3 days a week. Working from home 2 days a week. This means that the dog will never be alone at home..
Thanks for the advice - because some people we know told us that a pup can get used to living along for 6 to 8 hrs at home.
The pup is called "bangaari", which means "golden girl" (also a term of endearment) in our native tongue. She is about a month and a half old now.
Right now, she is a bit too young for long walks or jogs - just a couple of really short walks. And some playing around in the garden.
Will post a picture of the pup soon.
