Senior BJP leader Kailash Vijayvargiya on Monday likened sulking Bihar party MP Shatrughan Sinha to a dog as he landed himself in another controversy barely 24 hours after the party-led NDA was humiliated in the Bihar assembly polls. The dog analogy was used by Vijayvargiya, a BJP general secretary and a party strategist for the Bihar polls, days after he was forced to withdraw his controversial tweets targeting Bollywood superstar Shah Rukh Khan.
