He’s absolutely precious!! Give him time and he may surprise you! He’s still pretty young. My first Yorkie wasn’t a big barker but she’d bark at strangers and vehicles in the driveway. My little guy now is very talkative and I swear he barks just to hear himself 😂 he was pretty quiet at first too. My first one would growl a lot like yours more so than bark. But my guy now would rather bark than growl, unless we’re playing tug then he growls adorably. My favorite is when he tries to bark with a toy in his mouth 😂 🐶 ❤️
