I rescued a boston terrier with mange, I use spirulina in his food and he gobbles it down. He is clearing up , I used ivomec in piece of weiner then cut up a little bit of weiner on top of the dry good with spirulina over the weiner pieces.. He is such a cutie. was a puppy they were about to put him down when I got him.
Update: no green poop so far, and Guinness is now clear of all mange, his coat is looking nice and glossy these days with daily fish oil and spirulina still part of his regime. There are definitely no negative side effects so far, as to if the spirulina is making any difference alone, hard to tell
