I really do not think that KJC was being rude at all. Just simply trying to point out that an accident can occur here. Yorkies are tough little ones but easily injured! They are fragile! I don't think that Murphy would hurt this puppy intentionally...clearly this is a very docile and sweet pupster! The point is that the size difference is SO vast and one simple move can injure Stormy.
I would just encourage the OP to keep the rough housing down a bit. Just my opinion...and no, I am not saying to separate those two...very cute together!
