Lilly's been acting normal all day. She had been running around playing and everything like normal then got tired so she got up on this box beside the couch and layed down and went to sleep. Next thing I know my boyfriend and I look down and she's standing there licking up her own vomit. I know them cleaning up their own puke is common... I looked to see what she puked up and it was a treat that we had given her before she layed down since she had peed on her potty pad. Does anyone know why she puked or what? I'm going to pay close attention to her to see if she pukes anymore but I'm just wondering if maybe the treat was too big (my boyfriend didn't tear it in half like we usually do) or something.
