Lentils for Dogs: A Complete Guide
Amongst the earliest crops ever cultivated by human beings, lentils have been a staple food for people around the world for thousands of years. Affordable, versatile and packed with nutrients, they’re also an excellent source of plant-based protein, fibre, vitamins and minerals for dogs. A nutritious addition to homemade dog food, they provide valuable fibre, slow-release carbohydrates — important for sustained energy — and a range of essential nutrients that complement high-quality animal protein.
Can dogs eat lentils?
Yes, dogs can safely eat well cooked lentils as part of a healthy fresh food diet says our in-house dog nutritionist. Whether you’re preparing homemade food or adding a small amount as a topper to an existing diet, cooked lentils can be a beneficial ingredient, particularly for any dog fed a plant-based diet.
Health benefits of lentils for dogs
Support digestive health
Lentils are an excellent source of dietary fibre. Fibre helps maintain healthy digestion, supports regular bowel movements and nourishes beneficial bacteria living in the gut.
Provide slow-release energy
The complex carbohydrates found in lentils are digested more slowly than simple sugars. This provides a steadier release of energy throughout the day, making lentils a useful ingredient in homemade food for particularly active dogs.
Help maintain a healthy weight
Because lentils are filling and relatively low in fat, they can help increase the volume of food without adding excessive calories. When combined with lean animal protein and vegetables, they may be useful in carefully managed weight-control diets.
Rich in vitamins and minerals
Lentils contribute important nutrients such as folate, iron, magnesium and potassium, all of which play essential roles in normal body function.
Although no single ingredient provides everything a dog needs, lentils can make a valuable contribution to overall dietary diversity.
Encourage variety
One of the many benefits of making homemade food for a dog is the ability to rotate ingredients.
Including lentils alongside other dog-safe carbohydrates, vegetables and proteins helps create a varied diet that exposes dogs to a broader range of nutrients.
Nutritional value of lentils
Different varieties of lentils have slightly different nutritional profiles, but they all offer a similar combination of beneficial nutrients.
Lentils are particularly valued for their:
- High fibre content
- Slow-release carbohydrates
- B vitamins
- Iron
- Potassium
- Magnesium
- Polyphenols and other naturally occurring plant compounds
Because they digest more slowly than many refined carbohydrates, lentils can provide sustained energy while helping dogs feel satisfied for longer after eating.
How much lentils can dogs eat?
Unless your dog is fed a wholly plant-based diet, lentils should generally make up no more than 10% of its overall caloric intake. (See the 10% rule of homemade dog food).
Remember though, dogs have eaten what some like to term “human foods” for thousands of years. Wherever legumes like lentils and chickpeas were a staple of the human diet, they would also have been a staple of the canine diet. Don’t be afraid to experiment to find out what works best for your dog.
That said, if you are new to making homemade food for your dog and you are looking for a starting guide:
- Small dogs: one or two teaspoons of cooked lentils.
- Medium dogs: one or two tablespoons.
- Large dogs: a few tablespoons as part of a complete meal.
The exact amount will depend on your dog’s size, energy needs and its overall diet. If you feed your dog mainly commercial food and are looking to use lentils as a topper, use the above guide. If you feed your dog a full-time homemade diet, stick to the 10% rule.

How to feed a dog lentils
Lentils are an outstanding, budget-friendly source of plant-based protein, iron and dietary fibre.
Here are four creative, dog-safe ways to feed lentils to your pup:
1. Lentil & Chicken Savoury Mash
Plain, whole lentils can be a bit boring for a dog. Blending them with a lean, aromatic protein creates a highly nutritious, iron-rich gravy that turns any kind of dry food into a gourmet meal.
- Boil 50g of brown or red lentils until completely soft. In a food processor, blend the cooked lentils with 50g of boiled chicken breast and 4 tablespoons of the cooking water.
- Blend into a thick, smooth puree. Ladle a warm tablespoon of the mash directly over your dog’s regular food. It adds a powerful hit of folate, magnesium and protein to their bowl.
2. Frozen Lentil & Bone Broth Gut-Health Bites
Lentils are packed with soluble fibre which acts as a prebiotic to feed the good bacteria in your dog’s gut. Freezing them into small bites makes a great, low-fat summer snack.
- Stir 2 tablespoons of fully cooked, cooled red lentils into 100ml of homemade bone broth.
- Pour the mixture into silicone mould and freeze for 3 hours. Pop them out as a refreshing, crunchy treat that will help improve stool quality.
3. Sticky Lentil & Pumpkin Lick Mat
When cooked thoroughly, red lentils naturally break down into a thick, paste-like consistency that spreads easily across textured rubber enrichment toys.
- Mash a small handful of warm, fully cooked red lentils with a fork. Mix the lentil paste with one tablespoon of pure pumpkin puree or a smear of xylitol-free peanut butter.
- Use the back of a spoon to press the thick paste firmly into a rubber lick mat, then freeze for 45 minutes. The repetitive licking action stimulates the release of calming hormones, making it perfect for distraction during stressful events such as nail trimming or baths.
4. Baked Lentil & Oat Training Drops
Cooked lentils act as an excellent binder for home-baked cookies, allowing you to create high-protein, budget-friendly training treats.
- In a mixing bowl, combine 100g of thoroughly mashed cooked lentils, one medium chicken egg and 120g (1 cup) of oat flour.
- Roll the dough into tiny, marble-sized balls and flatten them onto a baking sheet lined with parchment paper. Bake at 180°C (350°F) for 20 to 25 minutes until golden and crisp. Allow them to cool completely before rewarding your dog.
Preparing lentils is straightforward.
1. Rinse thoroughly under cold water.
2. Remove any small stones or debris.
3. Cook until soft.
4. Allow to cool before serving.
5. Use as a topper to mix into a homemade meal.
Properly cooked lentils should be soft enough to mash easily with a fork.
Frequently asked questions
Q. Can puppies eat lentils?
A. Yes, puppies can eat lentils.
Q. Can senior dogs eat lentils?
A. Yes, senior dogs can eat lentils. Many senior dogs benefit from the fibre and steady energy release that lentils provide. If your senior dog has difficulty chewing, cook lentils until very soft so they blend easily into the meal.
Q. Can dogs eat lentils every day?
A. Lentils can be included regularly provided they form part of a varied, balanced diet. Rather than relying on lentils as the only carbohydrate or fibre source though, it is far better to rotate them with ingredients such as oats, brown rice, quinoa, sweet potato and pumpkin to provide greater nutritional diversity.
Q. Can dogs eat red lentils?
A. Yes. Red lentils are perfectly safe once cooked thoroughly and are often one of the easiest varieties for dogs to digest.
Q. Can dogs eat canned lentils?
A. While I would always prefer to use dry lentils, dogs can eat canned lentils provided they are rinsed under running water to help remove excess sodium.
Q. Can dogs eat raw lentils?
A. No. Lentils should always be cooked before feeding to a dog.
Q. Are lentils better than rice for dogs?
A. Neither is inherently better. Lentils provide more fibre and plant protein, while some dogs find rice easier to digest. The best choice depends on your dog’s individual needs.
Q. Can lentils replace meat in homemade dog food?
A. For most dogs, lentils should complement — not replace — high-quality animal protein. Animal ingredients remain the primary source of essential amino acids and other key nutrients in a balanced homemade diet. That said, some dogs thrive on a dog nutritionist-designed plant-based diet.
Q. Which lentils are best for dogs?
A. Several varieties of lentils are suitable for dogs. These include: Red lentils, Green lentils, Brown lentils, Puy lentils and Black (Beluga) lentils. Red lentils soften quickly and are often the easiest to digest. That and their generally lower price point make them a popular choice of lentil for use in homemade dog food.
