Why is my dog vomiting water with high liver and kidney levels?

Updated on September 23rd, 2025

Pet's info: Dog | Pomeranian | Male | unneutered | 1 year and 7 months old | 5 lbs

My dog is ! had an elevvated Alt and Bun. He had bilious vomitting syndrome as a puppy and now hes been vomitting every morning after he drinks water theres no food in it. He eats at 5 am gets his water at 9 and vomitts the water up. Hes also on pepcid twice a day. Hes on a round of metronidazole for 30 days I think he may have SIBO. my other poms have had it from the same breeder. His apetite is ok hes a super picky eater. His last set of labs in March were all normal.

Hello, thank you for your question about Loki.

ALT is a liver enzyme and elevations can be a sign of underlying liver disease (caused by infection, inflammation, etc). BUN is considered a marker of kidney function but can also be elevated for other reasons, such as GI bleeding. Depending on the severity of these elevations and Loki's history I would recommend testing him for an infection called leptospirosis, as this disease can cause liver and kidney abnormalities.

Alternatively, If Loki is still feeling well and the metronidazole is improving his symptoms, you could continue with this treatment regimen and monitor him for development of any symptoms. I would recommend rechecking these values after he has finished the course of metronidazole and considering the need for other diagnostics at that time.

Hope this helps, good luck!
