Forgot to add.
I have 2 yorkie-poos one Zoey weighs 10 pounds and Bella weighs 4. We have a chocolate lab that just came into our home,he's 10 weeks and weighs 11 pounds already

Although he is and is going to be a bigger dog,I fully trust him around mine. He yaps and picks and them both BUT,Zoey knows whose boss and so does he.
She just barks at him and he'll walk away! So funny!
