Chlorella for Dogs

Chlorella is type of single cell algae. It is harvested from fresh water. It is very high in nutrients and useful as a natural remedy for a variety of health problems in dogs. It is a simple remedy for a variety of health problems in dogs including arthritis, low energy and overexposure to heavy metals.

Nutrients in Chlorella

Chlorella is a concentrated source of nutrients including the following:

  • Protein
  • Iron
  • B Vitamins
  • Vitamin A
  • Vitamin C
  • Phosphorus
  • Potassium
  • Magnesium
  • Chlorophyll

Why Should I Give My Dog Chlorella?

Chlorella can make up for nutritional deficiencies in dogs. Poor quality diets and stress can leave dogs lacking in important nutrients. Toxins from pesticides, herbicides and vaccinations can be quite an assault to a dog’s immune system. In addition to the nutritional properties of chlorella, it is an excellent remedy for detox.


The iron, b-vitamins, and protein make chlorella a great supplement to renew the energy of a dog. Energy may also be restored when a dog consumes chlorella and reduces his toxin or heavy metal load.

Vaccine Detox

Vaccines can be a stress to the immune system and a source of heavy metals. Chlorella strengthens the immune system and helps to remove poisonous metals.


The iron content in Chlorella is helpful for dogs with anemia. Dogs with severe flea problems are especially susceptible to anemia.


Bad breath or other odors from your dog can be helped with chlorophyll, of which Chlorella is a good source.


Chlorella can help dogs with arthritis by increasing the nutrition they receive and improving their pH.

How Much Chlorella Should I Give My Dog?

Start with a small amount of chlorella and increase the amount as needed. Watch your dog for side effects whenever you introduce a new supplement.

  • Small Dogs – 500-1000 mg
  • Medium Dogs 1000 -2000 mg
  • Large Dogs 2000 – 3000 mg

What Kind of Chlorella Should I Give My Dog?

Chlorella comes in tablets, powder or made into special treats for dogs. You should choose a way to dose your dog that he is mostly likely to take and you are most likely to remember. Most dogs readily accept supplements made into treats, though you should make sure that other ingredients in treats would be suitable for your dog. Many dogs are easy to give pills to. Mixing chlorella powder into your dog’s food may be the easiest way to get him to take it.

Amazon sells a few varieties of chlorella for dogs and cats. Sun Chlorella makes Rejuv-A-Wafers and Green Mutt Pet Nutrition sells treat wafers for both dogs and cats.

I have a 12 year old Lhasa Apso and for the past few months she's been experiencing pain in her legs and her behavior has changed all she did was sleep and eat..and then my mom suggested me feed my dog chlorella. On the 3rd day (today) I noticed my dog alive again, she's playful once again and running. Woo hoo! I'm so glad this works, I only been giving her half a tablet but I think I will go up a dose.

Hi I have been a Nutritionist for 21 years I have several dogs on chlorella for years and it it very safe and it is also a nutrition power house for health. My husband and I also have taken it for years. So yes you should continue to give her this supplement and you can up the dose a little bit. I hope I was some help to you.

I used to give my dog a little chlorella powder mixed in her food (with water) when she was younger and noticed an increase in energy. At some point she refused to eat food with it added and so I bought a barley grass formula for dogs. Seems to work well for a little while but as she ages she's getting picky about food. She started refusing her food again when I added the powder.

Cholorella: I started my 1 year old pup on this because of the positive results I am having on myself. I gave her one 500mg tab and it did not make her loose. I want to send my brother for his 15 year old baby.

I had a blue wolf dog and he had one thousand chlorella pills a month, he loved them and ate them freely every day. He was a very big, strong dog and never had any health problems. When I had him castrated the vet said she dare not give him any more anaesthetic, as she had given him enough to put a horse down and he was still conscious. Eventually, he drifted off and the job was done.

Chlorella for dogs: My aunt's maltese got into rat poison. His body began to shut down, he lost his hair, his tongue turned black and the end fell off...the vet told her he could be of no help and would make a house call if she needed him put down. She used a large syringe with no needle to give him water with a high concentrated amount of the brand Sun Chlorella, for pets. I'm not sure what else she may have done to help nurse him back to health, we are all naturalists in the family and its probably not the only remedy that contributed, but he recovered and she contributed it to the chlorella entirely. It took a while for the hair to grow back (the tip of his tongue never did) and he never looked the same, but he lived a happy 10 more years.
