Safe-Guard (Fenbendazole) Dewormer Liquid is a solid choice for horse owners looking to manage a variety of intestinal parasites. With its active ingredient, fenbendazole, this liquid dewormer effectively targets common parasites such as stomach worms and lungworms. Its oral drench form makes administration straightforward, which is particularly beneficial for those who may be new to horse care. The product is designed to be used safely with adult horses.

One of the strengths of this product is its extensive spectrum of parasite control, making it a versatile option for horse owners. Additionally, the zero-hour milk discard time for dairy cattle is a significant advantage for those who need to manage both horses and dairy cows. However, it’s essential to keep in mind the residue warnings, such as the slaughter restrictions for cattle and goats. This may limit its use in certain farming operations, especially for those considering the meat and milk production aspects.

While this dewormer comes with clear instructions, it's always wise to consult a veterinarian before starting treatment, particularly for horses with existing health issues or in specific weight ranges. There are no established withdrawal periods for pre-ruminating calves, making it unsuitable for some types of livestock, which could be a drawback for some users.

Dosage Form

Most important from

Dosage Form
This wormer works great for my horses. The tubes are easy to measure the correct amount and the paste is easy to administer.

The Durvet 6 Pack of Ivermectin Paste is a reliable choice for horse owners looking to manage parasite infestations. One of its standout strengths is its broad spectrum of effectiveness against various worms and bots, including large and small strongyles, pinworms, and even lungworms. This makes it particularly suitable for horses of all ages, from young foals to breeding stallions, ensuring safe usage across different life stages. The apple flavor is an added bonus, as it helps reduce resistance and makes administration easier, creating a more pleasant experience for both horse and owner.

However, there are some considerations to keep in mind. While the paste is designed to be easy to use, some horses may still resist treatments regardless of flavor, necessitating additional strategies for administration. Also, being a paste, the dosing might require careful measurement to ensure effectiveness, particularly for horses on the edge of the weight range. Additionally, while it offers effective parasite protection, it does not address all types of parasites, so owners should remain vigilant about their horse's overall health and consider additional treatments if necessary.

The Durvet Ivermectin Paste provides comprehensive parasite control and is user-friendly, making it an excellent choice for horse owners. Just remember to monitor your horse's response and remain aware of the need for occasional resistance management to keep your equine companions healthy.

Buying Guide for the Best Horse Dewormers

Choosing the right horse dewormer is crucial for maintaining the health and well-being of your horse. Dewormers help to control and eliminate internal parasites that can cause a range of health issues. When selecting a dewormer, it's important to consider several key factors to ensure you are choosing the best product for your horse's specific needs. Understanding these factors will help you make an informed decision and keep your horse healthy and parasite-free.
Active IngredientThe active ingredient in a dewormer is the chemical compound that targets and kills parasites. Common active ingredients include ivermectin, moxidectin, fenbendazole, and pyrantel. Each of these ingredients is effective against different types of parasites. It's important to know which parasites are prevalent in your area and which ones your horse is most likely to encounter. Consulting with a veterinarian can help you determine the best active ingredient for your horse's specific needs.
Parasite SpectrumThe parasite spectrum refers to the range of parasites that a dewormer can effectively target. Some dewormers are broad-spectrum, meaning they can treat a wide variety of parasites, while others are more specialized. If your horse is at risk for multiple types of parasites, a broad-spectrum dewormer may be the best choice. However, if your horse has a specific parasite problem, a targeted dewormer might be more effective. Understanding the parasite spectrum of a dewormer will help you choose the right product for your horse's needs.
Dosage FormDewormers come in various dosage forms, including paste, gel, liquid, and pellets. The form you choose can depend on your horse's preferences and how easy it is for you to administer the medication. Some horses may be more accepting of a paste or gel, while others might prefer pellets mixed with their feed. Consider your horse's temperament and feeding habits when selecting the dosage form to ensure successful administration.
Frequency of AdministrationThe frequency of administration refers to how often you need to give the dewormer to your horse. Some dewormers are designed for monthly use, while others may be administered less frequently, such as every three to six months. The frequency can depend on the type of parasites being targeted and the dewormer's active ingredient. It's important to follow the recommended schedule to ensure effective parasite control. Your veterinarian can provide guidance on the appropriate frequency based on your horse's specific needs and risk factors.
Weight RangeDewormers are often dosed based on the weight of the horse. It's crucial to know your horse's accurate weight to administer the correct dosage. Underdosing can lead to ineffective treatment and resistance, while overdosing can cause toxicity and adverse effects. Many dewormers come with weight-specific dosing instructions or syringes marked with weight increments. Weigh your horse or consult with your veterinarian to determine the correct dosage for your horse's weight.
Resistance ManagementParasite resistance to dewormers is a growing concern in the equine community. Overuse or misuse of dewormers can lead to parasites developing resistance, making treatments less effective. To manage resistance, it's important to rotate dewormers with different active ingredients and follow a strategic deworming plan. Working with your veterinarian to develop a deworming schedule that includes fecal egg count tests can help monitor parasite levels and reduce the risk of resistance.
