Both my girls did that too, but as they get older they will stop. Best to start their training now, YOU MUST SHOW WHO THE ALPHA IS…There is a lot of information on the internet watch
National Geographic Channel - Animals, Science, Exploration Television Shows they have lots of training for dogs on it. Don’t give up on these little guys, you’re a heck of a lot bigger and I’m sure smarter. Even on Yorkietalk they have great ideas. I’m sure you wouldn’t give up on your children if they misbehave.
