Just in case you need an excuse to dress up your dog in a costume while walking around Clarendon, there’s an event for that. Plus, it benefits two Arlington nonprofit organizations.

The Howl-O-Ween Walk runs from 9:00-11:30 a.m. on Saturday, October 25. Doorways for Women and Families teamed up with Homeward Trails Animal Rescue for the fundraiser, which also serves to raise awareness about domestic violence against women, children and pets.

The trick-or-treat event begins at James Hunter Park in Clarendon with coffee, bagels and a kickoff ceremony. Walkers and their pets will follow a one mile route, picking up treats at selected businesses along the way. Festivities continue back at the park with snacks, doggy goodie bags, a demonstration by the Arlington County Police K-9 Unit and a doggy costume contest.

Online registration is $30 for adults and $20 for children under 16. This year, people also can create an online fundraising page in their pet’s honor. The top fundraisers can win prizes including hotel stays and gift cards.

Sue Bell, executive director of Homeward Trails, said domestic violence victims and their pets will have something new to celebrate at this year’s event: the enactment of a pet protective order law in Virginia.

“This bill allows companion animals (dogs and cats) to be added to protective orders in the case of domestic violence… something that in the past has resulted in victims staying in a dangerous situation longer in order to protect their pets from harm,” Bell said via email. “We will be having Del. Patrick Hope and [state] Sen. Barbara Favola speak on this at the kick-off of the walk. It’s a huge victory for both human and canine/feline victims of domestic abuse!”
