Dog Preventive Parasite Control Welfare

Preventive parasite control protects dogs from heartworm, fleas, ticks, and intestinal parasites that cause significant welfare suffering.

Key Facts

Heartworm is transmitted by mosquitoes and causes severe cardiac and pulmonary disease
Flea infestations cause intense pruritus and secondary skin disease in affected dogs
Tick-borne diseases including Lyme disease and babesiosis cause serious systemic illness
Intestinal parasites including roundworms cause malnutrition and may be zoonotic
Year-round parasite prevention is recommended for dogs with ongoing exposure risk

Welfare Considerations

Parasitic disease causes significant welfare suffering ranging from intense itch from fleas to cardiac failure from heartworm. Prevention is far more effective than treatment for most parasites. Year-round parasite control tailored to individual exposure risk protects dogs from preventable suffering throughout their lives.

What You Can Do

Maintain year-round flea and tick prevention as recommended by your vet
Use heartworm prevention in geographic areas where it is transmitted
Conduct regular worm egg counts to guide anthelmintic treatment decisions
