A new study found that having this can cut down on family arguments. What is it? A pet. According to a new study, kids generally like the family pet more than their siblings, especially if it’s a dog. The researchers found that kids love their siblings, but still see them as competitors for everything from new toys to getting love from their parents. They don’t have those issues with a dog. It gives them unconditional love and companionship, and they feel like they can safely share secrets with the dog, even though it doesn’t understand.
