Good news for families that would love to have a furry dog or cat but hesitate for fear the kids might become allergic: Fido or Kitty might actually be good for children’s health, scientists say. They found that children who were exposed to animals at a young age had lower rates of nasal allergies as adolescents. “Family pets, in particular dogs...need not be removed to prevent allergies, and in fact may protect against them,” Melanie Matheson of the University of Melbourne, lead author of the study, told Reuters Health in an email.
