Hello, thank you for using Petco Pet Education Center, formerly Petcoach. If Sancho's liver values are elevated due to the ingestion of some foreign material, be it a plant or other toxin, & he is eating with no vomiting or diarrhea, your veterinarian may be taking a wait & watch approach. Usually, we will administer emetics ( to induce vomiting ) & an intestinal absorbant such as charcoal if this was an acute issue. But often we do not see these elevations for hours to days after an insult to the liver has occurred. If Sancho is well, rechecking the values in several weeks is prudent. The values may change by this time. If not, we need to see if this is a chronic issue with the liver, or possibly even the gall bladder. Medications may be need ed at this time, including some neutraceuticals such as Sam-e and milk thistle. It is important that you stay in close contact with Sancho's veterinarian for any recommendations. Take care.
