There are a handful of supplements that all dogs need daily and one of them should provide a healthy dose of chlorophyll for your dog.  This article discusses the tremendous benefits of adding super foods that include this powerhouse of health benefits to your dog’s daily diet and why your four legged friend must have it.

What is chlorophyll?

First, a little bit of background is in order.

Chlorophyll is actually the green pigment found in the chloroplasts of algae and plants.

It is critical in the process of photosynthesis, helping plants absorb energy from light sources.

But it’s also extremely helpful for human beings and  animals.

50 or so years ago, scientists started to unpack some of those benefits. They discovered that chlorophyll could fight certain infections, like strep or staph infections, and learned of some more cosmetic benefits like the combating of bad breath. It fought gum disease and got right of putrefying bacteria in the digestive tract. It was even linked to the healing of wounds, stimulating protective tissue growth.

So, what are the benefits of chlorophyll for dogs?

Now that you know a little more about chlorophyll in general, you might be wondering if it’s safe for dogs. After all, there are plenty of substances out there that are good for people but are simply no good for dogs and other pets.

The good news is that chlorophyll is not only safe for your dog; your dog needs it to thrive.Consider the things we already know chlorophyll does, for instance. It keeps your dog strong with a healthy immune system.  This is critical because a strong immune system guards your dog against illness and disease.

The benefits of chlorophyll for dogs are pretty much the same as they are for people:

  1. Protects against cancer (this is a biggy)
  2. Regenerates red blood cells
  3. Provides energy for your dog
  4. Cleans and detoxifies the bloodstream and eliminates free radicals
  5. Cleans the digestive tract
  6. Heals wounds
  7. Fights infection and disease
  8. Helps with colon health and stool problems
  9. Cuts out grazing and grass eating
  10. Helps with oral health and gum disease
  11. Every organ in the body benefits from it

How do I give my own dogs chlorophyll?

There are a number of ways to make sure that your dog is getting his or her daily dose. The addition of barley grass can provide some of this wonderful green element, while alfalfa is also beneficial. We’ve talked a bit about alfalfa for dogs before, as some of you may remember.  Either form or both is good.

Other options include the crushing of a tablet to be placed on top of your dog’s food or the addition of liquid chlorophyll to the dog’s water. With regards to dosage, I give my 100 pound lab 1/2 teaspoon in the am with her food and another 1/2 teaspoon with her dinner.  IF YOU CHOOSE TO FEED BARLEY GRASS AND LATER NOTICE MORE SCRATCHING — STOP THE BARLEY GRASS AND SWITCH TO ANOTHER GREEN FOOD SUCH AS SPIRILINA OR CHLORELLA!

As with the addition of anything new to your dog’s diet, proceed with care. Adding chlorophyll certainly has its benefits, but it’s better to err on the safe side and start with small dosages and increase over the next couple of days until you reach the full dosage.

NOTE: DON’T get sucked into thinking that feeding your dog those rawhide treats they now have on the market calling them chlorophyll treats are an alternative – THEY ARE NOT! There’s a tiny bit of chlorophyll in those amongst a lot of ingredients that aren’t good for your dog including rawhide and sugar. GIVE THE REAL DEAL!

Here’s another article that includes more information on the benefits of chlorophyll for dogs.

    I have a small fussy dog and if I put anything in her water to drink, she won’t drink it! only has to e water….so if I have a tablet to give her in some ham or chicken, will this work and be as good??

    can you also recommend a good trusting company in the UK to supply this?


  • Paulina

    I have a 4 pound, 18 month young maltese can u tell me how much liquid chlorophyll I can safely add to her water (to help clear her brown eye stains, particularly) please? thank you

    • janie

      Hi Paulina:

      I would try add a few drops of the liquid chlorophyll (2-3) to her water and see if it helps.


  • rogerio

    Hello I’m from Brazil and I have an 8 kg dog with hypothyroidism, say that chlorophyll is a spectacle for this disease and various dermatitis?

  • dianna

    so i can go to a health shop and buy chlorophyll off the shelf for my dog?

    • janie

      Yes, providing it’s natural and comes from a good source.

  • Kim

    I just purchased liquid Chlorophyll, based on my breeder group 2 tablespoons a day was fine for my 62 pound girl. I just put it in her food, it would be wasted in the community water bowl. Now as I read your article I see how my other girls can benefit from it also.
    They range from 70 to 90 pounds. I was going to start them all on a tablespoon per meal, is that too much?

    • janie

      That should definitely be okay to start Kim, then work your way to the 2 tablespoons for each of the other dogs as well.


  • Max Jones

    I had no idea that chlorophyll was so important for dogs, and that it could help prevent cancer! I’ve been looking into some green algae dog treats, and I think these have the necessary vitamins in them to help protect our dog. I’m going to have to do a little more research into the green algae dog treats, and if they do indeed have chlorophyll, I’ll have to make an order!

  • Carla Ferrier

    There is also a company called that offers spirulina wafers in addition to a complete supplement (longevity)) amongst other things. The cost is reasonable and free items are given when you get to certain dollar amounts. Just another available option.

      Hi Carla:

      Thanks for sharing! 🙂


  • karen hoppe

    And she has been eating grass for awhile, but she doesn;t throw up ….and the vet recommended for her allergies, change her food , which I did, she is on the purina pto plan with salmon for sensitive skin and stomach…..

    • yourolddog

      Can you afford to feed her a better food Karen – not dry, but something such as The Honest Kitchen?

      How much does she weigh? This could have a huge impact on her allergies. I can share some ideas with you. I would get her away from dry completely and I would most definitely get her away from Purina.

  • karen hoppe

    Is it good for allergies such as pollen, and others, see my dog has had been on Apoauel for her allergies, she is always biting her feet, and tail and anal area. and the Apouel is very expensive and she also suffers from chronic ear infections, and she was diagnosed with occluded ear canals, and vet said only alternative was ear canal abbalation and that is very expensive and riskyand have to go to Oklahoma or Dallas for the surgery, and even though i clean her ears , it can’t get into the ear canals because it is blocked any advice so in the meantime all i can dois just make sure she is comfortable and happy, other than that she eating and everything normal….

    • yourolddog

      Hi Karen:
      Can I ask what you feed her and do you include any supplements?


      • Geri

        My girl has terrible allergies. Started feed raw 2 months ago and it had really help. Also get medicated bath every other week

        • janie

          Hi Geri:

          That’s great to hear! Raw works wonders for most dogs.

          Thanks so much for sharing!


  • Munchkin(my dog's name)

    I have liquid chlorophyll and give my chiahauhaua a capful in his water and his bad breath stopped immediately. I thought it was just a coincidence! I am so glad! Now I feel so grateful I found your sight to know that it is not only safe but helpful to his health. Maybe it will help him process his food better and lose weight. He’s had a weight problem ever since we’ve moved to Florida since I can’t walk him much. I am not well. This is the blessing I was looking for and he loves it. Thank you so much!

    • yourolddog

      Hi Munchykin:

      Thank you so much for sharing your comment about your experience with chlorophyll. I’m so glad it helped you.

      However, you might want to keep an eye on his teeth and gums if his breath is continuous problem. Just like us, they too need regular maintenance on their teeth. Bloody gums (Gingivitis) cause bad breath, but also contribute to a lot of bigger problems including heart issues.


  • Robin

    How much chlorophyll should be added to the diet? I’m getting some now in powder form and going to add it to my dog’s diet. He’s 70 pounds.

    • janie knetzer

      Hi Robin:

      I’m not sure what brand or what type of chlorophyll you’re buying, or if you’re purchasing the brand I recommended “Starwest Botanicals”? Is it Barley Grass or another form of chlorophyll?


      • Robin

        It’s not the brand you recommended. I’ll figure it out. I don’t feel like being scolded for getting a brand that isn’t as good as others. I’m doing the best that I can.

        • janie knetzer

          I wasn’t going to scold you, but okay. Good luck.


    Is chlorophyll the substance that dogs get from eating grass. I notice my dogs eating grass.

    • janie knetzer

      Hi Gus:
      Yes, they do get chlorophyll from eating grass and I firmly believe that’s why they eat it, because they need it and they’re not getting it from their diet. Just adding a little barley grass to your dog’s daily diet can make a tremendous difference in his overall health.
