It was a costume party for the dogs as Santa Clara’s Wag Hotels held its 4th Annual Haunted Howloween Party on Oct. 26. With local vendors, adoptable animals, trick-or-treating for pets, photos with Cruella de Vil, “wag swag,” prizes and a costume contest, dogs and their human companions enjoyed light snacks and beverages for two hours last Thursday. Prizes were given for most original, funniest, scariest and best owner/dog combo costumes. One-hundred percent of the proceeds were donated to Humane Society Silicon Valley. Wag Hotels is at 2000 Duane Ave. in Santa Clara.
