Keep your dog and Halloween separate. Even the gentlest dogs might mistake trick-or-treaters for genuine threats. And when nervous, some dogs can get irritable and snap. Be sensitive to your dog's stress level. Keep him in a quiet, separate area of the house, away from windows and the front door.

Don't play dress up. It might look cute, but costumes can make your dog extremely uncomfortable - or worse, can constrict their breathing. Don't dress up your dog unless you are absolutely certain that he won't find it distressing.

Keep your dog on a leash. And walk your dog only when you are unlikely to encounter trick-or-treaters.

Give him a treat. Give your dog a special treat filled with something tasty to keep him occupied and relaxed.

Watch out for candy. Chocolate is toxic to dogs. If you have children at home, make sure they don't leave any sweets lying around. Also, the day after Halloween there are likely to be candies and broken eggs on the streets. Be diligent in steering your dog clear of them.
