Hill's Prescription Diet l/d Liver Care is a wet therapeutic food for adult dogs diagnosed with liver disease. It's a vet-prescription formula — used under veterinary direction to support dogs whose liver function needs dietary management rather than as a general maintenance food.

The formulation is built around high-quality, highly digestible protein at controlled levels, which reduces the workload on a compromised liver while still meeting a dog's amino acid needs. Added copper is kept low and zinc, L-carnitine and antioxidants support liver cell function and repair. The canned format is soft, aromatic and easy to eat, which matters for dogs whose appetite has dropped as a symptom of their condition.

Owners feed l/d on their vet's recommendation, usually after bloodwork or a diagnosis has flagged liver involvement. The wet loaf format is often chosen for dogs who've gone off dry food, and can be fed alone or alongside the matching dry diet for variety.
