They both may look cute and sweet, but Lauren Alaina’s dogs – Prissy the Shih Tzu and Bella the Pomeranian – are actually nothing alike, especially when it comes to doggie dress-up.

“Prissy, when you put a bow in her hair, she’ll put her head on the ground and run around like a bulldozer until the darn thing has a big knot and falls out,” the American Idol alum tells PEOPLE. “But Bella will leave the bow in, she’ll just chew her clothes off. They’re total opposites.”
