Pet's info: Dog | Cairn Terrier | Male | neutered | 20 lbs
My dog suffered vomiting and diarrhoea for 2 weeks, loud stomach noises but was still eating. Started drinking more but then his stomach noises became very loud. Bloods showed ALT levels 7 times higher than normal levels. And high urea levels. Then he suffered 2 seizures within 10 hours. The vet said he should be put to sleep. So I did. He was a 15 year old cairn terrier. .Please help me understand what he may have been suffering from.

I'm sorry to hear that Charlie's surgery was postponed, but looking at these results, I agree that it's best to first investigate further. I see that both Charlie's ALT and GGT are elevated. Both of these enzymes increase with insult to the liver from a variety of different causes, such as chronic hepatitis or hepatitis, among others. When both BUN and creatinine increase, kidney disease is the cause. In Charlie's case, his creatinine is normal, so kidney disease is less likely the cause of the BUN increase, but it could indicate very early kidney disease. It is possible that his BUN increase could be associated with his diet, particularly a raw diet, but diet won't impact liver enzymes to that degree. Additional testing is certainly needed. At this point, I assume that your vet has likely recommended rechecking these values in a week or so, and may have also recommended a urinalysis and abdominal ultrasound to try to get to the bottom of this issue. There's no need to panic - additional information is just needed. I've attached links to a few articles about interpreting blood test results that may be helpful to you. I hope that everything goes well for Charlie!
