A dog that roars

Meet 'Tiger' a canine who awoke curiosity by not barking, but roaring. Wow! Tiger belongs to a farmer in Karwar called Pundalik and is reported to look like a tiger with yellow and black stripes. What is more? It roars when provoked.
Lets do the guess game now. Was the mother a tiger or was it the father. If the mother was the dog, must I say that we have a real desperate tiger on the move. Watch out. And if the father was a dog...just imaging what guts the dog had to bang a tigress. Now that is what I call brave heart.
