Another type of algae used in fish food is Spirulina.

Spirulina is a bluish-green alga found in most ponds.

It is what makes pond water greenish and slimy.

While Chlorella for dogs is healthy, Spirulina is dangerous for any pet, besides fish, to ingest.


Spirulina or blue-green algae poisoning in dogs can cause;

  • Vomiting
  • Diarrhea
  • Panting
  • Excessive drooling
  • Dizziness and disorientation

In severe Spirulina poisoning, dogs can suffer seizures, respiratory failure, and liver failure.

The worst-case scenario is death.

-Kurt Kobain



Premium fish food brands use whole fish instead of fish meals.

This is a healthy source of proteins and omega 3 fatty acids for your fish and dog.



Besides whole fish, fish food brands also use crustaceans like squid and krill as protein boosters.


Krill are tiny crustaceans that look like shrimp.


Both squid and krill are rich sources of omega 3 fats which are good for your dog’s skin and coat.



Worms are a popular ingredient in fish food because…well…we use it to bait fish!

Blackworm and earthworm carry the same nutritional value as a high-quality fish meal.

When grounded up and processed, worms are not toxic to dogs.



🐶 Important

Live worms can be dangerous to dogs. Besides heartworms, the larvae of earthworms when ingested by dogs can cause sickness.




Insects like the Black Soldier Fly are added to fish food for a protein and calcium boost.

Dogs too can snack on Black Soldier Fly larvae.

The high protein and calcium content in BSF larvae is healthy, especially for puppies.
