I am currently dog sitting my friend's Yorky. She is between 6-12 months old and has been wee wee pad trained. She poops and pees on the pad, but three times now in the last two days has become so excited seeing me return home that she lost bladder control and a few drops came out. She relieves herself fully on the pad, it seems like she doesnt even realize these few drops but can tell that I get upset. She actually has a corner of my living room picked out to hide in. I dont yell at her or raise my voice but she seems to be able to tell that I am not happy when this happens. I do reinforce using the pad which works fine so far. Anyone else run into this? Once this occurred when I returned home and came into the bedroom and found her in teh bed with my girlfriend and she got so excited right then that it happened. Another tiem I came home and lifted her up on the bed and it happened again. The third time was tonight, we came back from dinner, she ran over to my girlfriend and licked her hand then she came over to me jumped up at my leg, I did not encourage this excitement, just kinda waved to acknowledge and not completely ignore (am i nuts to wave?) and still after seeing me a few drops leaked out!!! Only with me, not my girlfriend!!! My friend, she never told me that she has any excitability accidents so I believe this to be a new development and dont want to return her dog with a new problem. Any ideas? Help?
