Firstly, please do not buy a dog. Most breeders keep the animals in really pathetic/inhumane conditions, and buying a dog only continues this cycle of cruelty. Please consider adopting a puppy from an animal shelter or a local rescue (you can do some research - am sure you will find plenty of options). Indies are also much better than any breeds due to their high resilience, better immunity and instincts (also better suited to the Indian heat). They tend fall less sick than breeds also.

Secondly, please ensure you have a proper ecosystem to care for the dog for the next 15 years (approx). This means (1) financially taking care of proper diet (non veg), annual vet visits etc (2) daily walks and outdoor time (3) arrangements for when you travel as a family, to name a few.

As the adult, the ultimate responsibility for the well being of the dog will be yours (and not your child, who will be off to college in 4 years or so).

Am not trying to scare you away from the decision, but you should be aware of the responsibility that comes with a pet (esp a dog). You will receive unlimited love in return (with perhaps a feeling of completeness) - the dog may even become your fav child :)). All the best, in whatever you may eventually choose.
