Well, my dear sweet Daisy(being called PRINCESS PIA(PAIN IN A@@)) right now is driving us nuts.  She is 10 months old and for the last week she has been WHINEY, trying to air hump everything and anyone.  Thought it was a dominance thing,  not sure.  She is up my butt everywhere I go. She is eating fine, bathroom fine, she came out of first heat the beginning of March.  Anyone have an idea why she is like this?  I need to mention her sister, which my parents have is also going through the same thing and she also came out of heat in March.  Any help would be helpful.  We get onto her for the humping motions but it only stops temporarily.  As i sit here typing, she is trying to wrap her feet around me and is whining.....HELP!!!
