Can dogs eat liver?
Maybe — liver is one of the most nutrient-dense foods you can feed a dog, packed with vitamin A, iron, and B vitamins. However, it's so rich in vitamin A that excessive feeding can cause hypervitaminosis A — a toxic condition that damages bones and joints. Small, infrequent portions are key.

Benefits and risks
Benefits
- Exceptionally rich in vitamin A, iron, and copper
- Highest natural source of B vitamins, especially B12
- Contains high-quality protein with all essential amino acids
- Rich in folate and riboflavin
- Extremely palatable — dogs love the taste, making it an excellent training treat
Risks
- Very high vitamin A content — can cause hypervitaminosis A if overfed
- Hypervitaminosis A causes bone deformities, joint pain, and muscle weakness
- High copper content can be dangerous for breeds prone to copper storage disease
- Rich enough to cause diarrhea and vomiting if introduced too quickly
- Some liver may contain residues from the animal's diet or medications
Recommended serving size
Adjust portions based on your dog's weight, age, and activity level. Treats and snacks should make up no more than 10% of daily calories.
| Dog size | Weight range | Serving |
|---|---|---|
| Small dog | Under 20 lbs (9 kg) | 1 teaspoon, cooked, 2-3 times per week |
| Medium dog | 20–50 lbs (9–23 kg) | 1 tablespoon, cooked, 2-3 times per week |
| Large dog | Over 50 lbs (23 kg) | 2 tablespoons, cooked, 2-3 times per week |
How to prepare and serve
Preparation
Boil, bake, or pan-cook liver (beef, chicken, or lamb liver) without oil, butter, or seasoning until fully cooked — no pink inside. Cut into very small pieces. For training treats, bake thin slices at 250°F for 2 hours until dry and chewy. Freeze-dried liver treats are a convenient commercial alternative. Keep portions small — liver should make up no more than 5% of total diet. Never feed liver pâté or liverwurst (too much salt and fat).
Frequency
2-3 times per week in very small amounts.

Frequently Asked Questions
- Liver should constitute no more than 5% of your dog's total diet. For a 30-pound dog, that translates to roughly 1 tablespoon of cooked liver a few times per week. The primary concern is vitamin A — liver contains 100-500 times more vitamin A per gram than muscle meat. Chronic overconsumption leads to hypervitaminosis A, which causes stiff joints, bone spurs, muscle weakness, weight loss, and digestive problems. Symptoms develop gradually over weeks to months of excessive intake. Acute toxicity from a single massive serving is rare but possible. Moderation is critical with liver.
- Beef liver and chicken liver are the most commonly fed and readily available options, and both are excellent. Chicken liver is slightly lower in vitamin A and copper, making it marginally safer for frequent feeding. Beef liver has the highest vitamin A concentration, so portions should be especially small. Lamb liver falls between the two. All types provide exceptional nutrition in small amounts. Avoid feeding liver from wild game unless you're certain the animal was healthy, as liver can accumulate toxins, parasites, and contaminants from the animal's environment and diet.
- Liver makes exceptional training treats because dogs find it irresistibly delicious, and small pieces pack enough flavor to motivate even the most stubborn learner. To make liver training treats, bake thin slices of chicken or beef liver at 250°F for about 2 hours until they're dry and slightly chewy. Cut into pea-sized pieces for small dogs, slightly larger for big dogs. Because liver is so rich, keep the total amount used in a training session within the daily safe limit. Freeze-dried liver treats from pet stores are a convenient alternative that last longer and are less messy.
