Bring smart cute puppies with excellent IQ home.

OK now excuse me....this is completely different question. Have no intention to change the direction of this thread but something abruptly hit me and I thought of taking help here.

My sibling who is in HYD is toying on the idea of adopting a dog. She has not done any research so far about the expenses but since someone told her that it is good for the kid to have a dog as a pet so she is considering that thought. I know that dogs come with price tag.
She is thinking of a labrador since that is supposed to be a very friendly dog...I have no clue except that they are huge dogs!

Can anyone here tell me how much does it cost monthly to have labrador as a pet dog? Please include all possible expenses including some amount kept aside for urgent unexpected vet visits too. I want to show her this post and use it as a guide to move forward with her plans. So, please come up if you know.
