When i got Layla i was also worried about all of their "unique personality traits" but i'm a big believer that ANY dog can be stubborn, yappy... ect... it's all about the training.... and since you've had a toy breed before you know their special quirks
but like someone said.. there are not over 20000 members on here for no reason! Having had layla for almost 2 years... i'll never own another breed.... Yorkies are amazing at stealing your heart when you aren't looking...
