Cowell, 54, apparently hired Edward Alava, who owns the Dog Store on the Upper East Side, to care for his two pups while he was in New York following the birth, reported the New York Post.
"Edward would come to Simon's hotel, the St Regis, to care for his two dogs and would walk them three times a day. Because of the snowy weather, Edward brought cashmere sweaters for the dogs and leather snow boots," a source said.
"Edward advised Simon on how to familiarise the dogs to Eric, telling Simon to put one of Eric's blankets in the pup's basket so they could get used to the newborn's smell.
