The Bayer Quad Dewormer is a chewable tablet that kills all kinds of worms, including roundworms, tapeworms and hookworms. It's highly effective and you don't need to have a vet prescribe it. You can just buy it off the counter
This is our recommendation, as it works well even for dogs that are three weeks old. Most brands don't allow puppies to ingest a dewormer until they're six weeks old or older. This is an excellent product for all breeds of dogs. It only requires a single dose, which is very convenient. You can give it to your dog as a chewable tablet or break up the tablets and pepper them on their food. Keep in mind, however, that some unpleasant side effects such as vomiting can happen.
