Buying Guide

Active ingredient matters

Choose a dewormer based on its active ingredient—ivermectin and fenbendazole (e.g., 10%) target different parasites and resistance profiles, so match treatment to your horse's needs and veterinary guidance

Consult your vet first

Have fecal egg counts or a vet assessment guide treatment choice and timing rather than relying on automatic rotation or routine schedules

Dose form and ease of administration

Paste formulations and flavored options (apple flavor or similar) affect how easily you can administer doses and how accurately you can deliver weight-based dosing

Pack size and dosing increments

Consider tubes per pack and dose-per-tube counts to ensure you can cover your horse's weight class without waste; multi-tube packs are common for multi-horse barns

Watch for resistance and treatment history

Track previous products and active ingredients used—repeated use of the same class (e.g., ivermectin) can contribute to resistance and affect future efficacy
