Dogs are loving, playful and loyal. Your significant other should be, too! “Dog Park,” an exposition on everything The Saturday Knights would do for their girls and their dogs, sounds like sweet summer love with a bite. It’s all canine: woofs, sly whistles, Barfly en falsetto, and heartfelt endearments. “I wouldn’t trade you for a Spanish Water Dog!” (How kind.) “Dog Park” is from TSK’s latest rock-infused hiphop concoction, Mingle, which just dropped just last week.
