Companion Animal Intestinal Parasites and Preventive Care

Intestinal parasites cause significant welfare harm in companion animals. Evidence-based preventive care protects animal welfare while reducing unnecessary antiparasitic use.

Key Facts

Roundworms affect up to 20% of dogs and are transmissible to humans, especially children
Tapeworms are transmitted through flea ingestion, linking flea and worm control programmes
Regular faecal egg count testing allows targeted treatment rather than calendar-based dosing
Antiparasitic resistance is an emerging concern in companion animals as in livestock
Indoor cats have significantly lower parasite burdens than outdoor cats with hunting access
Puppies and kittens require more frequent worming than adult animals due to higher exposure risk

Welfare Considerations

Intestinal parasite burden causes welfare harm through malnutrition, gut inflammation, and in heavy infections, obstruction and organ damage. Young animals are most vulnerable and can develop serious welfare compromise from parasite burdens that adult animals tolerate. Evidence-based parasite control using regular testing to guide targeted treatment rather than routine calendar dosing protects welfare while reducing unnecessary antiparasitic exposure that contributes to resistance development.

What You Can Do

Discuss appropriate parasite testing and treatment schedules with your veterinarian
Use faecal egg count testing before antiparasitic treatment where your vet recommends
Maintain regular flea control to prevent tapeworm transmission in dogs and cats
Worm puppies and kittens at appropriate intervals from an early age
Practice good hygiene including prompt faeces disposal to reduce environmental contamination
