Denosyl is a supplement containing S-Adenosylmethionine (SAMe), which is often used to support liver health in dogs. While lethargy is not commonly reported, every dog reacts differently to new supplements. If your dog's lethargy persists or if you notice any additional symptoms, it may be best to consult a veterinarian to ensure your pet's well-being and confirm that this is the right supplement for them.
