I noticed yesterday that Kobe kept scratching himself a lot, which started to alarm me. He would even cry a little. I turned him over on his back to inspect him for fleas when I noticed he was very RED and even had welts/swelling!!!! It also seemed that he was cutting himself with his nails, so he had some sores/scabs. I planned to take him this morning, but he wasn't scratching as much and the redness was gone. This afternoon, I noticed he's been acting REALLY strange; just laying around, looking sad, running around in circles like he's lost. Then he started dry heaving and just 5 minutes ago he vomited a yellow, thick liquid. He hasn't eaten and I have not seen him drink any water. Everyday I take him walking also...if that's important...
What could be wrong with him???
