The ratio of THC:CBD in resin is variable.
And the CBD inhibits the high of the THC as it's ratio increases.
It depends on the strain that it is extracted from, when harvested, how it is dried, and what extraction method is used.
The skill of the operator is a major factor as well.
That and the concentration of THC:CBD in the original resin is also variable.

So, every batch of oil is different in ratio, and concentration.
And you build a tolerance.
(I worked my way up to 1.25 Grams per day in 2 doses for a 190 pound male.)

Sound impossible to titrate?
It's actually not.
Weigh the dog, and do the math.
Then titration is easy.

Add one gram of oil to half a kilo, (about a pound) of butter.
Melt, stir, put it in the fridge.
That will give you about 2 milligrams of RSO per gram of butter.
If your oil 's concentration of THC is 50%, that makes 1 milligram of active ingredient per gram of cannabutter.
Then dosage is easy, almost all dogs love butter.

You will be able to tell when to back off, and when to increase dosage by the dogs reaction.

You have a good doctor there.
Do you know the location, and type of cancer?
