HEARTGARD Plus - (ivermectin/pyrantel)

Roundworms

What are roundworms and how can they affect dogs?

Roundworms are among the most common internal parasites of domestic animals. In fact, a type of roundworm called Toxocara canis infects more than 90% of puppies under 3 months of age¹ and roundworm eggs can be found in 15% of all dogs². The roundworm Toxascaris leonina is found in adult dogs.

Dogs become infected with roundworms through the placenta, nursing, or contact with feces of an infected animal. In dogs, adult roundworms live in the intestines and a large population can block the intestinal tract.

Signs of roundworm infection in dogs include: diarrhea, weight loss, worms in feces, swollen abdomen, vomiting, malnutrition, weakness and lack of appetite.

IMPORTANT RISK INFORMATION: HEARTGARD is well tolerated. All dogs should be tested for heartworm infection before starting a preventive program. Following the use of HEARTGARD, digestive and neurological side effects have rarely been reported.
