The external and internal parasites of domestic animals

Addison Emery Verrill's "The external and internal parasites of domestic animals" is a vivid, practical guide to the hidden world of parasites that affect everyday livestock and pets. Rather than treating parasites as vague “diseases,” Verrill explains how external pests and internal worms and protozoans live, spread, and damage their hosts—linking form, life cycle, and symptoms to what owners and veterinarians can actually observe. Through clear descriptions of the parasites' structures and developmental stages, the book helps readers understand where infection comes from, what conditions allow parasites to thrive, and why different animals can suffer in different ways. The external and internal parasites of domestic animals is an unchanged, high-quality reprint of the original edition of 1870.
