Joint supplement for an epileptic dog on phenobarbitone

Phenobarbitone is one of the medications where I'd want to flag a specific consideration before recommending anything. Long-term phenobarb use affects liver enzyme levels, and some supplements are hepatically metabolised in ways that can add load to an already-affected liver. Has the vet done recent liver function bloods as part of the epilepsy monitoring?

Mildly elevated but monitored and managed — that gives us a workable baseline. For a dog in this situation I'd recommend YuMOVE Senior and specifically flag it to the vet at the next monitoring appointment. The green-lipped mussel and glucosamine combination has a well-established safety profile and doesn't add meaningful hepatic load at the standard dose. What I'd avoid here is adding high-dose fish oil on top — omega-3 supplements at supplementation doses can occasionally add hepatic processing load that matters more when the liver is already under phenobarb pressure. Keep it simple: YuMOVE Senior, mention it to the vet.
