Martin,
I always worm with Ivomec 1% solution for cattle/swine on the first of the month at 1/10cc per 10 lbs of body weight... this a heartworm preventative.
The following week i'll worm with Safeguard/Strongid paste, about what you put on your tooth brush... this is for intestinal worms. I rotate the Safeguard and Strongid every month.
x2 This is the same routine and dosages I use except I use safeguard for two months and then switch to strongid for one month. I don't know why I do it that way. It would probably be easier to just switch every other month like Mike.
