Dogs regularly are diagnosed with intestinal parasites, including hookworms, roundworms, whipworms, and tapeworms. These parasites can cause gastrointestinal upset in healthy dogs, and in puppies and immunocompromised dogs, they can cause life-threatening health complications. Your dog can pick up these worms in several ways, including ingesting eggs from a contaminated environment, eating parasite-infected small mammals or birds, and from their mother during pregnancy. Roundworms, hookworms, and whipworms also pose a danger to humans, and children and pregnant women are at increased risk. While these intestinal parasites are a concern, protecting your family and dog is as easy as providing the appropriate preventive medication. Safe-Guard Dewormer is effective against roundworms, hookworms, whipworms, and taenia tapeworms.
