Young dogs and children go hand in hand. They are both full of energy. When introduced correctly, they can become the best of friends that will keep each other company through good times as well as the bad times.
Children who haven't ever been around dogs may become scared of a new dog, especially if the dog is almost as big as they are. Other children may think that dogs are toys, especially puppies. Both the child and dog need to learn how to behave around each other.
Children need to be taught how to carry a puppy and the right ways to play with them. For example, children should not behave aggressively around puppies because the puppy can get excited and start playing rough and may nip at the child. If the puppy is the type that nips, let the child know to scream even if it doesn't hurt. The screaming should stop the nipping.
If you are introducing an adult dog and instead of a puppy, you may need to be extra careful since you may not know the history and personality of the dog. Keep the dog tied up on a leash until you feel that it is safe to let the child play with the dog loose. As a precaution, whether a puppy or an adult, make sure an adult is present during playtime until you feel good about them playing alone together.
Each breed have different personalities. If you're choosing a new dog for a child, consider their size and personalities. Larger breeds for the most part do better with children, especially young children because the bigger the dog the more patient they are. Smaller breeds tend to be more snappish and can easily be hurt if a child falls on him. So if your choosing a dog for a child be choosy and pick the breed that's right for your child and family. Just remember, even if larger dogs are better for children that doesn't mean that smaller dogs are bad, it just means that you may need to put in some extra time for training, and they are trainable, so don't completely shy away from the smaller breeds.
