The bilirubin is a bit high, as is the ALP (alkaline phosphatase) but neither of these values is super specific in terms of what the cause or the best treatment is. We can see the ALP be elevated with stress, age, and sometimes even normal cell regeneration within the liver. The bilirubin can be slightly elevated when the blood sample is what we call "hemolyzed," which can sometimes happen when blood is spun down for a blood test to be run. Therefore, if he is still showing symptoms of illness, I would echo what Dr Ana said; it may be time to consider imaging. Either X-rays or an abdominal ultrasound maybe helpful in identifying the problem and therefore identifying the best way to treat it. Take him back to the vet if he's still having troubles, as he probably is in need of some more fluids as well. Thank you for asking Petco Pet Education Center, formerly Petcoach, I hope he's feeling better.

    Thank you for submitting your question regarding your dog. I recommend that he has further testing. X-rays of the belly are warranted in cases of frequent vomiting. Fecal testing may be necessary to look for intestinal parasites, bacterial or even a viral infection. If he is not current on his vaccines, parvovirus is a possibility. 48 hours is a long time to fast a dog unless they are recieving continuous IV fluids. Medication should be given to make him less nauseous and control the vomiting so that he will eat sooner. I hope this information helps. Good luck!
