A rescue dog can be the best idea for a home with children, and for a few reasons. Not only does it show children how to care for something else and draw out empathy and responsibility, but a rescue dog will have undergone behavior and aggression tests to ensure that they are safe to live with children. You will find that many rescue dogs cannot live with children, which could be due to them being too nervous or prone to aggressive responses. Those deemed suitable will be gentle, loving - a great example - and a friend for your child. Even with a litter of puppies, you don't know the dog's temperament; this is not the case with a rescue.
