A CBD:THC ratio of >20:1 tincture given twice a day would give your dog full efficacy after 2-3 weeks into treatment. Of course, you would continue to give the tincture twice daily, but may have to titrate the number of drops up after each 3 week period if you find break through seizures are occurring. Just a reminder…to treat seizures you must cross the blood-brain-barrier which entails you using a ratio of >20:1.
