Should I give my dog milk thistle for liver support on phenobarbital?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Female | 14 years and 2 months old | 18 lbs

My 14 year old Dachshund was put on phenobarbital two weeks ago and next week we go to have her blood checked. Do you think I should start giving my dog milk thistle since phenobarbital has been known to damage the liver over time?

In theory this would help a pet that is being exposed to a potential liver damaging drug. It definitely won't hurt. It can be expensive however. But it is a good proactive thing to do to potentially help protect the liver from damage over time. Best wishes with your pet Tootsie moving forward. Take care. : )
