So... I was recommended to get some sort of chlorella supplement for my dog who is apparently quite the ticket at the dog park and daycare. Bluntly: she was getting mounted at doggie daycare due to being, quote, very nice to everyone and not wanting to give "buzz offs." A year down, it seems to have really reduced the occurrence to the point that the staff has commented. Otherwise, she gets a glowing bill of health from her vet everytime, she has a super shiny coat, and seems to be pretty healthy.You just sprinkle the portion once a day over their food (I use wet for this) for five days on and two days off. The bag contains quite a bit for a 40lb dog. Appreciate that the bag itself reseals easily and that I could get it open without having to cut the zipper in the process. I went specifically with this one due to the quality of the ingredients and it hasn't let me down yet.
