Hats are not familiar objects to dogs, so if your dog doesn’t seem keen on wearing them, don’t get upset. Instead, show your dog that the hat is a positive thing. Place the hat near your dog and reward your dog for interacting with it. Repeat this for a few days, then try it on your dog’s head. If he keeps it on, reward him; if not, continue to repeat this action. Positive reinforcement is the best technique for getting your dog to warm up to the hat. It also helps if you previously trained your dog in basic commands like “sit” and “stay”. If you want your dog to keep the hat on for long periods, ensure that the hat is lightweight and fits comfortably. An adjustable chin strap will also prove helpful.
