I have been trying to keep Lucy in the house where it is cool as much as possible due to the heat. 93 today here in Pa. She was fussing to go out and I made her stay in. WELL, I should of listened to her b/c she threw up twice. Not much, and just yellow phlegmy stuff. She is eating, drinking, eyes clear, same old self. She has never been sick though so this is something new for me to deal with. I am thinking it is just from the heat, What do you think.
