If you have a dog that is scared of your child or other children, you must take the situation seriously and find ways to give your dog space from children so that he can learn to be more comfortable around the source of his fear. Be very careful when training your dog with children, and use only positive training instead of punishing your dog for showing negative behavior. Safety first, always supervise babies and young children around a dog and never leave them alone together, even for a moment. If your dog is scared of other children visiting your home, set up fail-safe management — gates, doors, physical barriers—between the children and your dog. Find a safe zone that your dog can go to where children are not allowed.
If your dog is scared of kids outside the home, keep him away from playgrounds and parks where children play. Never allow your dog to run around off-leash in or near a playground. Never allow kids to greet your dog or come into his space. Teach any kids that will be visiting your household to pay no attention to your fearful dog.
You can try to create a positive association with kids, if you have the right distance and calm children to help. Start having calm kids walk past at a safe distance, and when they pass, give your dog a high-value treat. Repeat this several times. If your dog seems nervous, move further away. Learn to read your dog’s body language and fear signals, so you know when your dog is becoming uncomfortable. If your dog shows any fear signals when around children, move your dog away immediately, without reprimanding your dog or the kids. If your dog continues to be afraid of children, seek the guidance of a positive trainer to help you with the process.
