Strongid Paste Dewormer For Horses

Strongid Paste provides effective parasite control for all horses, including breeding, pregnant, and lactating mares and foals of any age. This broad-spectrum dewormer targets mature infestations of large strongyles, roundworms, and pinworms. It is commonly used for a foal’s second deworming treatment, addressing roundworms in foals at 4–6 months of age and one month post-weaning. The paste formulation allows quick administration, making it suitable for horses that resist other methods. Always administer exact dosages based on body weight and follow with proper handling and monitoring for adverse reactions.
Farnam PyrantelCare Daily Dewormer For All Ages

Farnam PyrantelCare Daily Horse Dewormer in pellet form provides continuous protection against 31 common parasites, including large and small strongyles, ascards, and pinworms. Palatable pellets are designed to be easily mixed with daily grain, making it a practical option for horses that dislike paste or liquid dewormers. This daily approach helps maintain steady parasite control, but dosage should be adjusted to the horse’s weight and feeding regimen. Consider rotating with other active ingredients to address potential resistance patterns.
Farnam Pyrantel Care Daily 50 Lbs

This Farnam product mirrors the PyrantelCare daily concept in a larger 50-pound bag, suitable for multiple horses or larger barns. Daily administration supports ongoing protection against common parasites, particularly in environments where horses share facilities or graze on pastures with higher parasite loads. The pelleted format can appeal to owners who want a low-stress routine, but ensure accurate dosing for each horse’s weight. Routine fecal egg counts can help fine-tune the schedule.
Safe-Guard Equine Paste 10% Fenbendazole

Safe-Guard Equine Paste uses fenbendazole to control a range of internal parasites, including both large and small strongyles, pinworms, and ascarids. It is flavored to improve palatability and may be preferred for horses that resist paste products. While not pyrantel-based, Safe-Guard remains a trusted option for broad-spectrum deworming within a rotation strategy. Proper dosing relies on body weight measurements and manufacturer guidelines to minimize the risk of underdosing or resistance development.
Ivermectin Paste Dewormer For Horses

Ivermectin paste is a widely used broad-spectrum dewormer effective against bots and several stages of S. vulgaris. While it does not contain pyrantel, it is commonly included in parasite control programs as part of rotation schedules designed to reduce resistance. When using ivermectin, ensure accurate dosing by weight and consider fecal egg count data to optimize timing in coordination with pyrantel-based products to maintain long-term efficacy.
Ivermectin Horse Paste 6 Pack

This 6-pack of ivermectin paste provides bulk access to a trusted dewormer noted for its ability to clear bots and other internal parasites in a single-dose treatment. Like other non-pyrantel options, it is best used as part of a strategic rotation. Proper weight-based dosing remains essential to maximize efficacy and minimize resistance risk. Discuss integration with pyrantel-based products with your equine veterinarian.
Buying Guide
Key considerations when selecting a pyrantel-based wormer for horses include spectrum of parasites targeted, palatability, administration method, weight-based dosing, and rotation strategy. Weigh the following factors to optimize parasite control and animal welfare:
- Active ingredient and spectrum: Pyrantel-based products primarily target roundworms, large and small strongyles, and pinworms. Some programs combine pyrantel with other active ingredients for broader coverage.
- Administration method: Paste, pellets, and liquids each have pros and cons. Paste works quickly, pellets offer daily administration, and liquids provide flexible dosing for varied weights.
- Palatability: Horses that resist dewormers may respond better to flavored pastes or pellets designed for easy acceptance.
- Dosing and weight: Accurate dosing is critical. Use weight estimates or scales to determine proper dose. Over- or under-dosing can reduce efficacy and promote resistance.
- Rotation and resistance management: Do not rely on a single product year-round. Rotate active ingredients and integrate fecal egg counts to tailor the schedule to your herd’s needs.
- Age and health status: Some products are designed for foals, pregnant mares, or lactating mares. Ensure the chosen product is appropriate for the animal’s life stage and condition.
- Cost and barn logistics: Consider bag sizes (pellets vs. paste), the number of horses, and storage conditions. Palatable daily pellets can simplify administration for large barns.
In practice, a robust parasite-control plan may combine pyrantel-based products with non-pyrantel options in a rotation, guided by veterinary recommendations and pasture management strategies. Regular fecal examinations help verify efficacy and guide timing for booster acts or changes in formulation. This approach supports healthier horses, cleaner facilities, and a more effective long-term parasite-control program.
