Treating parasitic worms is a common occurrence in large animal, small animal and exotic veterinary practices. Worm infestations are regularly reported in dogs, cats, horses, cattle and a wide variety of exotic companion animals. 

Worms represent an ongoing threat to the wellbeing of companion animals, livestock and working animals, and they can impact the bond between humans and their companion animals due to the potential for cross-species infection (zoonosis).¹To prevent this issue from arising, many deworming practices have been developed over the years; these are important strategies in maintaining the relationships that owners and managers have with their animals.²

Worms in dogs and cats—the most familiar of companion animals—can cause suffering, illness and even death. Even healthy-looking dogs and cats may be carrying a worm burden. Many cat enthusiasts acquire kittens with roundworms due to the fact that the worms are passed to them in their mother's milk.

Animals become infested with worms in a variety of ways, including:

• Other infected animals
• Eating the larvae or eggs of worms (e.g. in infected feces or in grass)
• Eating raw meat, infected prey animals or infected parasites

Signs that a dog, cat or other small animal may have worms include:

• Weight loss
• Dry, coarse fur
• Increased appetite, weakness and diarrhea
• In some cases, infected puppies and kittens can have a distended abdomen or “pot belly”

Nearly all horses carry some degree of worm burden, with small numbers of worms being tolerated and causing no noticeable effect on the horse’s overall health. Larger infestations of intestinal parasites can cause a wide range of problems however, including ill thrift, colic, digestive issues, diarrhea and death.³

Exotic animal species are also becoming more and more common among pet enthusiasts and on properties that are being managed for recreational or commercial hunting. In the former, the stress of captivity coupled with a closed environment can lead to potentially heavy burdens of parasites with direct life cycles.²
