Is it time to re-evaluate anti-parasitic use in companion animals?

Abstract

Anti-parasitics are very frequently used in companion animals for both prevention and treatment of parasites. When compared with practices related to parasite control in farmed animals, strategic, risk-based use of anti-parasitics in pet dogs and cats instead of precautionary and calendar-based treatment, is not a mainstream approach. Evidence of growing drug resistance in parasites of these hosts and a realisation of the potential adverse environmental consequences of anti-parasitics used in pets provide reasons to re-evaluate the use of anti-parasitics in companion animals. In order to achieve this, consultation and dialogue with industry stakeholders, as well as animal owners, is required.
