Halloween going to dogs (cats, too)

This Halloween could be a howling good time for pet costume retailers.

More than 31 million people will be dressing their pets in costumes this year, according to a report issued by the National Retail Federation and Prosper Insights, which surveyed 6,961 consumers.

And they are projected to spend around $480 million on little doggie (and kitty) outfits, which translates into roughly 4 percent growth from last year.

Puccini, a 10-year-old Yorkiepoo, will be joining other Hell’s Kitchen pets on the streets of Midtown this Halloween.

“Last year, he dressed up in a little dinosaur outfit that my friend Beth made,” explained his mommy, Leslie Riddle, a former Radio City Music Hall Rockette.

“He won the Halloween party at his vet’s office last year,” she said proudly. “This time around, we’re leaning toward Dracula and his vampiress.”

“One of the biggest trends this year is the growth of spending on pet costumes,” said Prosper Insights Executive Vice President of Strategy Phil Rist. “Out of the Americans planning to dress their pets in costumes, millennials (25-34) are most likely to dress up their pets, the highest we have seen in the history of our surveys.”

Overall Halloween spending, which hit a record $9.1 billion last year, is expected to drop slightly, to $9 billion, in 2018.

While children will once again tend to dress up as princesses or superheros and adults as witches and vampires, expect dogs and cats to impersonate pumpkins (11.2 percent), hot dogs (7.4 percent) and bumblebees (4.9 percent).
