I have done a bit of research into this particular product for you. Luckily, (because the field is full of phonies) you have apparently gotten yourself some legitimate CBD. The vendor says that a drop is approximately 2 mg of CBD, however that’s not enough for any kind of effects in my experience, possibly for a very small dog, but not for one as big as your Kanji. Dosage for edible CBD runs about the same as for THC in humans, more like 10 to 20 mg as an absolute minimum, and I would personally use half of that for an 80 pound dog. There is no such thing as an “overdose” of CBD, so theoretically you could use as much CBD as necessary until you see the desired effect (which I assume is calming), remembering that it can take up to 3 or 4 hours to see effects. However…I have no idea whether the other ingredients (especially the essential oils) are safe for dogs, so I strongly suggest you research them specifically for canine use. Best of luck to both of you!
