BETTER BUT WITH SIDE EFFECTS
I tried garlic on my dog and it may have expelled worms but it also dried out his beautiful shiny coat. The best way to do it is the vet med drontal but you have to deflea medication at the same time or before, cause they'll get worm parasites from the fleas right away again. I also tried the liquid med sold over counter at some pet stores 1/4 of the price and effective.
