how much, 3 days in a row? 1 click? I used 2 days in a row on mine and my gsp still passes a few worms every few poops. Worm is still alive. they are small about double the size of a grain of rice.
Sounds like tapes to me. I tried safegaurd and panacure on 3 day intervals( over a month period) didn't work on the tapes for me. I bought the worm x from tsc and one pill took care of em.
X2, vet told me that safeguard won't help with tapes. Also, what kind are you giving? Cattle, horse, or goat, they are different strengths, but all are way less than what a dog need. For example, to worm a 60lb dog you need to use enough to worm 600lbs of the cattle wormer roughly, more on the horse wormer, and also different on the goat wormer. If you have the big tube that takes a gun, I give three clicks per dog per day for three days.
