Presenting Complaint

  • Vomiting

Pertinent History

  • Nitro was treated for pancreatitis by the referring DVM last week. He received fluids and Baytril. He recovered and was getting better when he started vomiting the last few days.
  • The owner thinks that maybe he introduced the regular dog food too soon and should have kept him on cottage cheese and rice longer.
  • Yesterday he began vomiting more and became very lethargic. He was taken to the referring DVM. Because the heart sounds were muffled, chest x-rays were taken which showed an enlarged cardiac silhouette.
  • The referring DVM gave him 1 L Lactated Ringer’s Solution IV and Nitro improved although he still appeared slightly shocky.
  • He was referred to the VMTH.
  • Blood work was done last week. The owner said the white cell count was elevated and the liver enzymes showed evidence of toxicity.
