HOBOKEN – Humans weren’t the only ones who got treats today. Pooches pranced and pounced around Church Square Park for Liberty Humane Society’s Bark in the Park pet festival. Animal lovers let their furry friends roam free in the dog park while children were let loose in a bouncy house. A DJ blasted music as the four-legged attendees either tasted treats, got new accessories from the handful of booths, or prepared for the 4 p.m. costume contest. A Jersey City police dog even joined the fun, showing the crowd — of humans and canine counterparts — how much he’s learned in his K9 training. When not petting the animals, children ran to their bouncy house, face-painting and drawing booth. The Liberty Humane Society had felines and pooches up for adoption as well. Bark in the Park is how LHS raises funds to cover the emergency costs that come with the animals they take into their care.
