Endoparasites in Ferrets

Pocket Pet · Mustela putorius furo · typical adult weight 0.60–2.00 kg

5 cited drugs treat Endoparasites in ferrets: Fenbendazole, Mebendazole, Piperazine, Praziquantel, Pyrantel Pamoate.

Gastrointestinal helminth and protozoal infections. Macrocyclic lactones, benzimidazoles, and pyrantel cover the bulk of nematode treatment; protozoal indications require dedicated drugs (metronidazole, sulfadimethoxine).

The overview above describes Endoparasites across species; the citations below are the ExoticRx dose rules scoped to ferrets — a reference list, not new species-specific clinical guidance.
