Train your dog to react to a pet camera without fear by gradually introducing him to it. Put the camera on the floor and let him investigate and sniff it, rewarding him for good behavior. Practice turning the pet camera on and off while you are in the room with your dog to ensure the mechanical noises do not scare him. If you have a camera with two-way audio, practice talking to your dog through it to ensure he gets used to it gradually. Reward your pup liberally for interacting with the camera and practice using the treat launcher feature, if your camera has one, too.
