  I can't help with the poo either, sorry.
 Hmm..I didn't really consider the submissive thing about rolling over, that makes a lot of sense.  It took me forever to get Reagan to roll over.  I prob started with it around 6 months maybe and she was at least a year old when she finally got it and sometimes she still won't do it.  I did take break here and there though since she didn't like it.
 
 What I did is have her lay down, then kinda coax her to lay on her side a little(if I had to I would physically move her so that she was laying on her side)  Then I would take the treat hold it in front of her nose then slowly roll it over her head towards her back.  She will try to follow it with her eyes/head then eventually, when the treat gtes far enough, she will roll over to get it.  Of course this is all in theory it doesn't always work, as you can see at least 6 months of it for us.  Sometimes I would give her a little push to get her going too.  Oh and I did notice that Reagan prefers to do it to one side so if you notice that with you pup stick you may want to stick to that side until he gets it down.
