What Causes Elevated Liver Enzymes in Dogs?

Elevated liver enzymes in dogs often result from toxins, medications, infections, or chronic diseases, detected via bloodwork showing rises in ALT and AST. Early signs include lethargy, jaundice, vomiting, or loss of appetite. Seek immediate veterinary evaluation for accurate diagnosis before starting any supplements. All products require veterinary prescription and professional supervision. Always consult a licensed veterinarian before administering any medication to your pet.

How Do Milk Thistle and SAMe Support Dog Liver Health?

Milk thistle (silymarin) acts as an antioxidant to protect liver cells and promote regeneration in dogs. SAMe (S-adenosylmethionine) aids detoxification, boosts glutathione production, and helps reduce elevated enzyme levels. Hero Veterinary combines these with antioxidants for enhanced efficacy in complex liver cases. All products require veterinary prescription and professional supervision. Always consult a licensed veterinarian before administering any medication to your pet.
