my 11 year old cocker spaniel became suddenly ill vomiting her water up with loss of appetite and diarrhea. My vet drew a comprehensive metabolic profile on my pet and discovered high liver enzymes/ She suggested a bland diet to start of chicken and rice however Phoebe won’t even eat .that We returned to the vet within 72 hours aftr the vomiting and diarrhea came back and they gave her lactated ringers under the skin, a penicillin injection and some blue pills to help the live enzymes. I am praying that these treatments work. She was also given a shot for nausea and one for inflammation. I am praying for return to health.

My 10yr. old cocker spaniel also has very elevated liver enzymes. We have been monitoring them for the last 6 months. We did an ultrasound last month which really didn’t show anything significant. The Dr. put him on 3 different antibiotics to see if there was an infection. He is scheduled for a repeat ultrasound on Tuesday and I just had his blood work done and his levels are still creeping up… so worried

My 10 yr old mixed breed just had geriatric bloodwork and his liver enzymes came back pretty high. He’s having an ultrasound on Wed. praying everything is ok.

So my 12 1/2 year old lab/retriever mix annual blood results came back for the second year in a row with raised liver enzymes not terribly high I don’t think. – no noteworthy increase year over year. Last year did not follow up with the vet recommended ultrasound and here I am again. At this stage in life, I have a dilemma. Separate issues with his sister. I’m trying to be pet realistic/cost responsible vs #lovemydogs. Any advice?
