Thank you all for your replies. I honestly wouldn't know what to do without this forum and the great advice of everyone here.
Update:
He continued a couple more times to do the same thing and it just didn't feel "okay" to me. I was on the phone with my vet (who is the ABSOLUTE best!) when Ranger began to heave violently as if he was going to throw up. Which he's never done. Ever. Before I could put the phone down and grab him, he vomited and passed out. My vet said to immediately put him in the car and meet her at the office (which is a 5-6min drive) he was lifeless y'all. After exam and X-rays the diagnosis is aspiration pneumonia due to vomit. He is doing "okay" now but it's very, very bad. You cannot even see his left lung on X-ray due to so much fluid. He is stable and on a TON of meds, oxygen tent and getting supportive care. We have no idea what caused the nausea, upset stomach or vomit as we've changed NOTHING at all. As most of you know this is very bad and can take a very long time to recover from. We need y'all. Our pack. Please, pray for my sweet boy. We are so worried for him. Thank you all.
