Don't get me wrong- I LOOOOVE my pookie

But how long do Yorkies generally
act like puppies? When do they start to calm down? I don't have much experience in this field. Both my mom's dog and my sister's dog are only a couple of months older than Marley ( who will be 6 months old on the 18th) and they are not nearly as hyper as Marley is. They are still puppies but they don't
act like it as much, you know? Do they start to calm down after you get them fixed?
Thanks in advance~!
