One of our concerns before getting Peiko, or a corgi in general is how well will he play with Polly (Our Chorkie Poo, that is just a fancy name for a chihuahua, Yorkie, and toy poodle.) She is not even 4 pounds and is fully grown. Don't get me wrong Polly is still incredibly spry and does a pretty good job standing up to her much bigger younger brother.

So I made the case to my wife that puppies will play rough and when one bites too hard, the other will yelp and stop playing, sending the signal that the play has got to rough and I do not like it. Well here is a problem, Peiko does NOT stop when he bites Polly to hard, she will often try to walk away but he just darts after her and continues pouncing on her, this escalates quickly because Polly gets incredibly angry because he won't let off of her and she tries to bite him hard back to tell him to back off. But his thick double coat and him flailing his weight around on her makes it pretty much impossible for Polly to prove her point.

Some times he will bite on her long neck hair and will not let go of her for awhile. This is incredibly annoying for Polly, my wife and I. His timing is bad, he almost always starts playing with her right when she is about to poop or pee, so often we have to segregate them in order for Polly to just go potty. 

Let me quickly clarify that he is not being aggressive to her, but he just does not seem to understand when she is done. We stop these actions quite often, but it seems like it doesn't stop his behavior. I have let it play out before to see if he gets the clue, but he just doesn't let up until she jumps to a high spot to get away from him. She really does want to play with him but it is to hard to stop it for her so she does gorilla tactics of starting a playing session then jumps on something and tauntingly barks at him.

They do love each other, and it does appear that Polly holds a higher pack status than Peiko does, since he doesn't seem to care anyways.

Another issue is when we take them to the park to run, he just heards her towards me, when in fact we just want her to be able to run strait to my wife. Polly doesn't even want to run at the park anymore because he just cuts her off and starts nipping at her anyways. She will only run if he is being held back.

I apologize for the length of this blog question, but I do not really know what actions to take and constantly reinforce to create a positive playing experience for both of them.

If anyone has any suggestions or past experience we could really use it. Thank you!
