Most sites tell you that when it comes to CBD oil you should give 1 to 5 mg per 10 lb of dog. My dog weighs around 50 lb so this is how I figured out how much I’ve been giving my dog and how much I should be giving my dog.
The product I have is CTFO CBD isolate drops at the moment 250 mg in the entire bottle. There are 30 ml in the bottle. Which breaks down at to 7.6 milligrams per one milliliter.
Now it says that a drop out of a dropper is .05 ml per drop, the average dose I give him is one suck up of the dropper and I measured this out at 36 drops. He obviously doesn’t hold his mouth open long enough for me to count out the drops as I administer them to him , but every time I suck up the solution in The Dropper, it fills about 3/4 of the way . Which means for every dropperful that I give him he’s getting 1.8 milliliters.
36 drops x .05 ml per drop=1.8
Now if I take the 7.6 milligrams per milliliter that I got by dividing the total number of milligrams which is 250 by 30 ml and multiply that by 1.8 ml which is his average dose I get 13.788 milligrams per average dose or suck-up of the dropper.
TOTAL (250) mg in bottle % total ml in bottle (30 )=7.666 mg per 1 ml
Since the dosage calls for 1 to 5 milligrams (low-end to high end) per 10 lb twice a day, for my dog that would be anywhere from 5 to 25 milligrams twice per day, or 10-50 mg per day. Since he takes this twice a day and I have just figured out that there are 13.7 mg per average dose, he is taking an average dose twice a day that is correctly in line for his weight and at 27.4 mg is actually a bit on the low end, but again, you are key in determining what works for your own dog.
Again this is for the solution that has 250 mg per 30 ml of solution. So if I got him a stronger solution, say one that says 500 mg per 30 ml, the dosage would obviously be doubled. Of course, the above dosage is only what is RECOMMENDED but it is really on a case to case basis. Only YOU know what is working for your dog, and CBD is not toxic, so overdose is not an issue. Of course, I suggest starting out with the smallest amount and building up to what works for your dog or it can become costly!
This is the easiest way I can explain this. I hope this helps someone.
