More: London and Milo are Brother and Sister and also are the best of friends. They love swimming in the lake, running and playing in the snow, chasing the ball and play fighting. London was selected by Massachusetts General Hospital to be a therapy dog. She visits patients before surgery to give them therapy and help keep them calm. She also visits schools to see kids before exams. These two dogs are the absolute sweetest Goldens we have ever met. They are just the biggest snugglers and just want to make everyone around them happy.
