I cannot recommend a dog for you if you have a child under age six.
That doesn't mean you shouldn't get a dog if you have a younger child! It only means I can't recommend specific breeds, because a dog's attitude toward young children is more a matter of the individual dog rather than its breed.
In my eBook, Dog Quest: Find The Dog Of Your Dreams, I've written a detailed article about finding child-safe dogs. If you're thinking of getting a dog and you have children, you should definitely read that article. It's an eye opener for sure.
You'll be receiving this eBook FREE as part of my Dog Breed Consulting Service, but if you don't qualify for this service because your child is under age six, you can still purchase Dog Quest here.
