Rex is vomiting tonight, too. STRANGELY grainy green vomit, which is not common for him. Wondering if he ate something when we pottied outside in the dark. I keep him on an expandable tether, but he still gobbles up any little thing (the more gross the better!) he finds before you can see what is happening to stop it. I gave him 1/4 a Pepcid, which is his old standby for recurring stomach problems. He's sleeping now. Hope some of us get some rest tonight. Must work tomorrow.
