IF I had a dog with any autoimmune diseases (and I do), I'd be leary of this. Peppers are nightshades and if a dog has any issues with immunity or other inflammatory issues, then it's not good for them.
The other thing that I have against this is the kelp. It's hard to find any sea vegetable companies that actually give the iodine amounts, and you can wreck their thyroids with too much.
Those things being said, yes. I'd give this occasionally to a HEALTHY dog.
