Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Liver (chicken, beef, lamb) is a nutrient-dense food for dogs, rich in protein, iron, copper, and vitamins A and B. Many dogs love the taste, and small amounts of cooked liver make excellent training treats. However, liver is extremely high in vitamin A, and feeding too much over time can cause hypervitaminosis A, leading to bone deformities, weight loss, and digestive problems. Liver should make up no more than 5% of a dog's diet. Always cook it thoroughly.
What You Should Know
While liver is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
