The following is a list of precautions recommended by numerous animal shelters and veterinarians designed to keep pets safe on Halloween.
THINGS THAT GO BUMP IN THE NIGHT
Trick or treaters can cause loud or excessive noise and frighten your pet, so try to keep your pets inside or in a place where they are insulated from the Halloween ruckus.
Pets, that are easily excitable should be kept from the front door so they cannot bite anyone or run into the street. With many people visiting the home in strange attire, even normally calm pets might overreact.
DEATH BY CHOCOLATE
Candy, especially chocolate, is toxic for animals and can cause vomiting, restlessness, heart disturbances, and even death. Ask kids not to share their candy with your pets.
JACK O’ LATERNS
Take extra precautions with lit pumpkins and candles, because pets can knock them over and start a fire. Ensure that all burning objects are out of pets reach. Try to confine a pet if it demonstrates an “unhealthy” interest in flames (e.g. it puts its paws in lit pumpkins or tries to play with candles).
DISGUISING YOUR PETS
Avoid costumes that are held in place with rubber bands which can be uncomfortable, and more importantly if mistakenly left on a pet can quickly burrow into the animal’s skin and cause injury.
If a pet wears a costume, make sure it is not constricting, causing your pet to trip, or blocking its vision. Do not force a pet to wear a costume if it demonstrates discomfort. All of the above can cause undue stress and possibly cause aggression in even the nicest dog, goldfish, or iguana.
EVIL LURKING IN THE NIGHT
Don’t leave pets outside on Halloween. Many animals disappear as pranksters and those with darker intentions tease, abduct, torture, or even kill pets.
Be especially watchful of black cats, which are frequent targets of cruel activities on Halloween. Try to keep black cats inside for the week of Halloween. Many animal shelters make black cats unavailable for adoption the week before Halloween because of black cat abuse
