Is there a gap in your dog's worm coverage?

Worms can be responsible for serious health risks to your favorite pet. Intestinal worms, such as hookworms, roundworms, whipworms and tapeworms, can pose a threat to your dog’s digestive system. These harmful parasites can cause your dog to have diarrhea, weight loss, anemia and more. Heartworms pose a serious health risk and can be fatal to your dog or puppy.

Unfortunately, worms may be more common than you think and many factors are responsible for their growing prevalence – from natural disasters to changing wildlife populations.

Treating and controlling worms is the best defense for your dog against these dangerous parasites. Stay informed about the dangers of intestinal worms and heartworms to understand why it’s important to keep your dog protected.
