The lung fluke Paragonimus kellicotti infects dogs living around the Great Lakes, in the Midwest, and in the southern United States. Flukes are flatworms ranging in size from a few millimeters up to several inches (2.5 to 5 cm) long. The fluke is acquired by eating aquatic snails and crayfish. Cysts develop in the lungs. Rarely, a cyst ruptures and causes a collapsed lung (pneumothorax).
The safest and most effective agent for treating all species of lungworms and lung flukes is Panacur. The drug must be given daily for 10 days. Prevent lungworms by cooking fish and restricting your dog’s hunting forays.
