I would treat it for at least 3 days in a row and then off for 2 weeks and another 3 days in a row. There is always a die off of the parasites and bacteria that give a flu-like symptom but the recovery is pretty quick.
Just like any dewormer or anti parasitic medicine you should always follow up with probiotics whether pets or humans as this type of medicine removes all bacteria good and bad.
The natural source for killing off cancer has been eliminated from our diets which is vitamin B17 contained in seeds. This is why all our fruits and vegetables have mostly gone seedless.
Try to order apricot seeds online if you can, they are a good source of vitamin B17.
Rule of thumb is you can eat as many seeds as you can the whole fruit without causing any adverse effects. Apricot seeds taste like a raw almond , I will use the eat three at a time a couple times a week just for maintenance.
Wouldn't hurt your pet too add some baking soda in their water & agave juice to sweeten to taste.
