That is so funny
Those little stinkers are so clever... My Suzi does not get a reward for peeing on her mat, because I have had no problems with her doing so. She does however, get praised when she poos on her mat. That is A big praise ! She has not tries to fake a poo though.
But, I have seen her many times lift her leg to pee... Yep Suzi, my girlie pup, will lift her leg . HA ha ha , it is the funniset thing . Oh well, whatever works , right
