How much liver can a dog eat? Working out a treat budget

How much liver a dog can eat depends on its daily calories. VCA Animal Hospitals says all treats together should be no more than 10 percent of those calories. Liver is rich in vitamin A according to USDA, so give it only part of that 10 percent. Your vet can give you the calorie number.

Start with your dog's calories, not its weight

You will see charts online that give grams of liver per pound of dog. We do not publish one, because we have not found a named veterinary source that gives one, and two dogs of the same weight can burn very different amounts. A working farm dog and a couch dog at 40 pounds are not the same animal at dinner time.

The number that matters is daily calories. You can get it in two ways. Your vet can give you a target from an exam, which is the better number. The feeding chart on your dog food bag is the rougher one: it gives a daily amount, and the calorie content per cup or can is printed on the bag too.

Once you have that number, the rest is arithmetic.

A worked example

Say your vet tells you a dog needs 500 calories a day. Ten percent of 500 is 50 calories for all treats. Our label lists 81.6 kcal ME per ounce, so 50 calories of our liver is about 0.6 of an ounce, or roughly 17 grams. That is the ceiling for a day with no other treats, chews or table scraps. Most days have some of those, so the liver share comes down from there.

We give weights, not piece counts. Freeze-dried liver breaks into uneven chunks, so one piece can weigh twice what the next one does. A small kitchen scale settles it in a minute. Weigh out a day's allowance once, look at the pile, and you will know what it looks like from then on.

Why liver gets a smaller slice than other treats

The 10 percent rule is about calories. Liver brings something else into the picture. USDA FoodData Central lists 16,900 IU of vitamin A in 100 grams of raw beef liver. VCA Animal Hospitals notes that excess vitamin A is stored in the liver, and that trouble has been linked to feeding raw liver over weeks to months.

The Merck Veterinary Manual states the dietary requirement for dogs as 3,333 IU per kilogram of diet and says harmful amounts sit many times above it. None of that says a training session with liver is a problem. It says the sources care about heavy, steady feeding over time, which is exactly what a habit with no measuring can drift into. We go through the common worries in are liver treats bad for dogs.

So we suggest splitting the treat budget. Let liver be the reward for the hard moments, and let something plainer cover the rest.

Every day, or now and then

Owners do both, and we do not set a rule here, because the right answer depends on the dog. A few grams a day inside a measured treat budget is a very different thing from a handful whenever the dog looks hopeful. If you plan to give liver daily, ask your veterinarian whether that amount fits your dog's diet, and tell them the weight you have in mind.

Making a little go further

The bag says these are intended for intermittent or supplemental feeding only, and not intended as a complete and balanced diet. Small pieces stretch the allowance.

• Snap pieces by hand. Ours start medium sized and split without a knife, so a single chunk covers several rewards.
• For a small dog or a long session, crumble a piece into bits the size of a pea.
• Keep the day's portion in a pouch or a small container, so you are not reaching back into the bag.
• Sprinkle crumbs over a meal if you want the smell without the extra calories of a full piece. Count them anyway.

Storing an open bag

Reseal the bag after each use and keep it somewhere cool and dry. Use an opened bag within 30 days. The best by date is printed on the bag and is one year from production.
