Former F1 driver John Watson says Mercedes should ban Lewis Hamilton's dog from Formula 1 races.While Hamilton insists he is enjoying his new freedoms after quitting McLaren, driver-turned-pundit Watson is making the link between the new Mercedes driver's lifestyle and his current struggles in Formula 1.'NO PLACE FOR A DOG'Watson said: "There is no place for a dog in the F1 paddock. For one thing, it is not fair on the animal. It (also) shows that Mercedes is bending over too far to please Lewis. There is absolutely no way McLaren would have allowed it."Lewis has to decide if he wants to be an F1 driver or a hip-hop star. He went to Mercedes with the reputation of being a man who would get the job done. It's just not happening and he needs to start working out why."Team mate and 2013 Monaco winner Nico Rosberg, meanwhile, is winning praise in F1. Adrian Sutil's manager Manfred Zimmermann said: "The way Nico has Lewis under control is the surprise of the season. It also shows that Michael Schumacher was not so bad in his last three years."
