How much spirulina should I give my dog?

An effective dose of spirulina depends on your dog's size and activity level. Generally, you should start with a dose of 1/8 teaspoon per 20 pounds and increase or decrease the amount as needed. It is best to start with a smaller amount and then increase it gradually over several weeks. You should also consult with your veterinarian before introducing spirulina into your dog's diet.

What happens if I give my dog too much spirulina?

Large quantities of spirulina can cause health issues such as vomiting, diarrhea, and loss of appetite.
