Hi Julie,
There are two possibilities. Normally, to figure out which is likely, I use a response to acupuncture as my guide:
- Damp Heat, which you would 'prove' as being present by seeing the pulse moderate in response to standard Damp Heat points, most notably the draining of Stomach 36, but also points like SP 9 and BL 25. Si Miao San is the formula for this, but success even with acupuncture would imply a food sensitivity. Usually food sensitivities in seizuring dogs are to the processed starches found in kibble and canned diets. I see the owner is feeding a blend of both. Generally, any consumption of kibble wipes out the benefits of a raw diet.
- Shao Yang disharmony, which lately we've been addressing with a modification of a new formula, called Chai Hu Gui Zhi Gan Jiang Tang. It seems to be more effective, although we are still accumulating case experience. You'll know to try this approach if it is tonification of GB points that improves the pulse. It's possible that this mechanism of seizures is not as impacted by diet
The timing of the seizures suggests it is actually Spleen deficiency with Damp Heat that is more likely, and that part of the exacerbation might be from diet, and part might be from prolonged use of Spleen cooling formulas. Even though you've just seen the dog, I would get him back in your office for the above acupuncture experiment, so you have some certainty going forward.
With either of the above approaches, you could probably stop the existing formulas.
