New box for dogs that are between 25 to 200 lbs. Treats tapeworms, roundworms, hookworms, and has two flavored chewables per box. I bought two boxes but only needed one treatment for my hound and that did the trick. I’m certain we caught it at the beginning. Gross but I’ve included a picture of the worm we saw and so far we have not seen anymore. I treated her the same day we saw it. And trust me you will pay a lot more at the vet and Walmart!
