How much wheatgrass should I give my dog?


Wheatgrass has become an increasingly popular superfood for both humans and dogs in recent years. It is packed with nutrients like vitamins, minerals, antioxidants, and chlorophyll. Some of the potential benefits of wheatgrass for dogs include improved digestion, reduced inflammation, increased energy levels, and better immune system function.

However, there are some important things to consider when giving wheatgrass to dogs. The appropriate dosage depends on the size and health status of your individual dog. Wheatgrass can be given fresh, frozen, dried, or as a juice powder. It’s best to start with small amounts and slowly increase to ensure good tolerance. Speak with your veterinarian before introducing wheatgrass, especially if your dog has any underlying health conditions.

This article will provide a thorough overview of wheatgrass for dogs, including the suggested dosing based on weight, different preparation methods, safety precautions, and potential side effects. A handy dosing chart is also included to help determine the appropriate amount of fresh wheatgrass, wheatgrass juice, or wheatgrass powder for your dog.

Nutritional Content of Wheatgrass

Wheatgrass is the young grass shoots of the common wheat plant, Triticum aestivum. It contains a dense amount of nutrients, including:

  • Vitamins A, C, E, K, and B complex
  • Minerals like iron, magnesium, calcium, potassium, zinc, copper, selenium, phosphorus, and sodium
  • Antioxidants and phytonutrients including flavonoids, amino acids, chlorophyll, and enzymes
  • Fiber
  • Chlorophyll – the green pigment with anti-inflammatory effects

This stellar nutritional profile is what makes wheatgrass so beneficial. Dogs can absorb these nutrients from wheatgrass just like humans. Many of the vitamins, minerals, and phytonutrients provide antioxidant and anti-inflammatory effects to support whole-body health.

Potential Benefits of Wheatgrass for Dogs

Here are some of the main therapeutic effects that wheatgrass may provide for dogs:

  • Improves digestion – The enzymes, fiber, and nutrients in wheatgrass can stimulate better digestion and nutrient absorption.
  • Boosts immunity – Wheatgrass contains antioxidants and nutrients that can strengthen the immune system and help fight disease.
  • Detoxifies the body – Wheatgrass may help remove heavy metals and toxins from the body through its cleansing effects.
  • Increases energy – The nutrients in wheatgrass provide a natural energy boost.
  • Fights inflammation – Chlorophyll and antioxidants have anti-inflammatory properties to reduce swelling, pain, and chronic inflammation.
  • Aids in weight management – The fiber and nutrients can improve satiety and metabolic function to support weight loss or maintenance.
  • Improves skin and coat health – Nutrients like vitamin A, zinc, and selenium support skin cell turnover and healthy hair/fur growth.
  • Supports dental health – Some claim wheatgrass may help reduce plaque buildup and fight gingivitis.

Studies validating these effects specifically in dogs are limited. But the nutrient content and anecdotal evidence suggest wheatgrass can provide meaningful benefits for dogs. Always monitor your dog carefully when introducing wheatgrass to watch for positive or negative effects.

How to Give Wheatgrass to Dogs

There are a few different ways to feed wheatgrass to dogs:

Fresh wheatgrass – This is the best option in terms of nutritional content. You can grow your own wheatgrass at home or purchase it. Simply chop or blend the fresh wheatgrass leaves and serve it to your dog.

Frozen wheatgrass – Freezing preserves the nutrients in wheatgrass. Thaw the frozen wheatgrass before serving.

Dried wheatgrass powder – Look for a reputable brand of dried, organic wheatgrass powder. Reconstitute the powder with water before giving it to your dog.

Wheatgrass juice – You can juice fresh wheatgrass at home or purchase bottled wheatgrass juice. Some dogs enjoy drinking wheatgrass juice.

Wheatgrass supplements – There are some dog supplements that contain wheatgrass along with other superfoods or nutrients. Only give supplements made specifically for dogs.

When trying wheatgrass for the first time, start with a small amount and work up slowly. Observe your dog’s reaction and adjust the dosage accordingly. Mixing wheatgrass into their regular food may make it more palatable.

Wheatgrass Dosage for Dogs

There is no official standardized dosing for wheatgrass for dogs. The amount you give should be tailored to your individual dog based on their size, health status, tolerance, and how it’s being administered. Here are some general wheatgrass dosage guidelines:

Fresh or frozen wheatgrass:
– Small dogs under 20 lbs: Start with 1 tsp and work up to 1-2 tbsp
– Medium dogs 20-50 lbs: Start with 1 tbsp and work up to 2-4 tbsp
– Large dogs over 50 lbs: Start with 2 tbsp and work up to 4-6 tbsp

Dried wheatgrass powder:
– Small dogs: Start with 1/4 tsp and work up to 1/2 tsp
– Medium dogs: Start with 1/2 tsp and work up to 1 tsp
– Large dogs: Start with 1 tsp and work up to 2 tsp

Wheatgrass juice:
– Small dogs: Start with 1-2 tsp and work up to 1-2 tbsp
– Medium dogs: Start with 1-2 tbsp and work up to 2-4 tbsp
– Large dogs: Start with 2-4 tbsp and work up to 4-6 tbsp

Divide the total daily amount into 2-3 doses given throughout the day. When using fresh wheatgrass, keep it stored in an airtight container in the fridge and use within 2-3 days.

Here is a handy wheatgrass dosing chart for dogs based on weight:

Dog Weight Fresh/Frozen Wheatgrass Dried Wheatgrass Powder Wheatgrass Juice
Up to 10 lbs 1-2 tsp 1/4 tsp 1-2 tsp
11-20 lbs 1-2 tbsp 1/2 tsp 1-2 tbsp
21-40 lbs 2-4 tbsp 1 tsp 2-4 tbsp
41-60 lbs 4-6 tbsp 1-2 tsp 4-6 tbsp
Over 60 lbs 6-8 tbsp 2 tsp 6-8 tbsp

These are general guidelines for healthy dogs. The dosages should be decreased for dogs who are older, smaller breed, or have underlying medical conditions. Puppies under 1 year old should not be given wheatgrass.

How to Prepare Wheatgrass for Dogs

If serving fresh or frozen wheatgrass, you’ll need to chop, blend, or juice it to make it easier for your dog to consume and digest. Here are some preparation tips:

– Chop using a sharp knife or food processor into small pieces.
– Blend into a slurry using a blender, adding small amounts of water if needed.
– Juice using a wheatgrass juicer or centrifugal juicer. Mix the juice with an equal amount of water before serving.
– Thaw frozen wheatgrass and chop or blend once thawed. Freezing breaks down the tough cell walls.
– For dried powders, follow package instructions to reconstitute with water into a paste or liquid.
– Mix wheatgrass into your dog’s regular food or serve it plain in a bowl. The taste may take some getting used to.
– Refrigerate fresh wheatgrass and use within 2-3 days. Discard if it develops a foul smell or appearance.
– Wheatgrass juice should be consumed immediately after juicing for maximal freshness and nutrient content.

Take precautions to avoid cutting your dog’s mouth on any grass blades when serving chopped or blended wheatgrass. Supervise your dog when first feeding wheatgrass until you see that they can consume it safely.

Are There Any Side Effects?

Wheatgrass is considered very safe for dogs, but some possible side effects may occur:

– Upset stomach or diarrhea – Start with small amounts and increase slowly. Reduce the dosage if digestive upset occurs.

– Allergic reaction – Dogs with wheat allergies should avoid wheatgrass. Discontinue use if any signs of allergic reaction develop like itching, hives, swelling, or vomiting.

– Mold content – Wheatgrass grown at home or improperly stored wheatgrass products can develop mold. This can cause illness if consumed. Ensure wheatgrass is mold-free.

– Pesticides – Wheatgrass grown conventionally may contain pesticide residues. Opt for organic wheatgrass when possible.

– Bloating or gas – The fiber content may cause temporary bloating. Make sure your dog is tolerating wheatgrass well.

– Dehydration – Wheatgrass has a diuretic effect and may increase urination and water needs. Ensure your dog stays well hydrated.

If your dog experiences any negative effects from wheatgrass, stop giving it and contact your vet if symptoms are severe. Start slowly with small amounts again once your dog is back to normal.

Is Wheatgrass Safe for Dogs with Health Conditions?

Wheatgrass is likely safe for most healthy dogs. But dogs with certain medical conditions should only have wheatgrass under veterinary supervision. Use caution feeding wheatgrass if your dog has:

– Diabetes – Wheatgrass may affect blood sugar regulation. Monitor levels closely.

– Thyroid dysfunction – High iodine content in wheatgrass may be problematic.

– Pregnancy/nursing – Insufficient data on safety for pregnant or nursing dogs.

– Upcoming surgery – Wheatgrass may interact with anesthesia due to its antioxidant content. Stop giving it 1-2 weeks pre-surgery.

– Kidney or liver problems – The detoxifying effects of wheatgrass may overburden impaired organs.

– Immunosuppression – Wheatgrass could potentially stimulate the immune system too much.

Check with your vet before introducing wheatgrass to a dog with any medical condition, especially if they are on medication. Stop giving wheatgrass if any adverse effects develop and let your vet know. They can advise you on the safety of continuing use of wheatgrass.


When given in appropriate dosages, wheatgrass can be a nutritious supplement for dogs. The vitamins, minerals, antioxidants, enzymes, and chlorophyll provide many beneficial effects. Start slowly and watch for any digestive upset or allergic reactions when introducing wheatgrass. Follow the dosage guidelines based on your dog’s weight and adjust according to their tolerance. Opt for fresh, organic wheatgrass when possible and proper storage to preserve nutritional potency. Avoid giving wheatgrass to puppies or dogs with health conditions unless approved by your veterinarian. With some caution and monitoring, wheatgrass can be a great addition to a healthy diet for your dog.
