Hi, and thanks for your question. These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.

    I would recommend that Gleason get checked out by a vet. Common causes of vomiting in dogs include dietary intolerance, dietary indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others. After examination, the vet may recommend bloodwork or x-rays to determine the cause of the vomiting. At the very least, he could receive an anti-nausea shot to give him comfort and you could watch him to see if the vomiting comes back. If it does, then he definitely needs to be re-evaluated to determine the cause.

    There can be very serious causes behind the vomiting in a senior dog such as kidney disease, liver disease, a GI illness, a foreign body, or even cancer. I would take Rocky into a vet today to get checked out. Best of luck.
