A spider and Harry Potter are the two costumes Australians are most likely to dress their pet up as this Halloween.

Using online analytics, money.co.uk determined the most popular pet costumes across the country with Spider, Harry Potter, Yoda, Lion, and Hot Dog making up the top five.

Mandi Wright, PETstock PETschool State Trainer, provided some tips on ensuring your pet is safe and at ease this Halloween.

“Ensure your pet is comfortable when wearing costumes and monitor them for the first few minutes of wearing it to ensure they don’t feel anxious or restricted.”

Wright also said as Halloween is more widely celebrated there is the chance there may be fireworks, which can be frightening for some dogs.

“If you have a puppy, it’s important to create positive associations to different people, sounds and places. Taking your puppy for a walk during the day will exposure them to different surroundings, just ensure that they are microchipped, and the details are updated in case they get spooked and try to run off.”

The coming-and-goings of trick-treaters also has the potential to upset anxious pets, so Wright suggests creating a safe environment for your pet to have some alone time.

“Giving them a chew toy and creating white noise is a great way to keep your dog distracted from what’s happening outdoors.”

Of course, it’s not just the pets dressing up, so Wright also has some advice for those owners who plan on getting into the Halloween spirit.

“If you’re planning on dressing up this Halloween, gradually introduce your costume or mask in a familiar place such as your home to make them feel comfortable. Rewarding your pet with treats while you’re wearing the mask or costume will help keep them relaxed.”
