Pierce’s All Purpose Nu-Stock has been around for decades, and it’s one of those products that animal owners tend to either swear by or approach with skepticism. This two-tube pack offers 12 ounces per tube, and it’s marketed for use on horses, dogs, cats, and other animals. The formula is a thick, dark, tar-like substance with a strong pine-tar smell, which is immediately noticeable upon opening. It’s designed to be applied topically for a range of skin conditions, including scratches, rain rot, girth itch, and hoof problems like cracks or thrush.
In practice, Nu-Stock is often used by horse owners for managing minor skin irritations and promoting hoof health. For dogs, it’s sometimes applied to hotspots or dry patches, though getting it to stay on can be tricky if the animal licks the area. The product contains sulfur and pine tar, which are known for their antiseptic and drying properties. It also includes petrolatum as a base, which helps it adhere to the skin but also makes it greasy and messy to apply. Users typically wear gloves and apply a thin layer with a brush or spatula, then cover it with a bandage or wrap if possible.
One of the key functional features is its versatility. It’s not a targeted treatment for a single issue, but rather a general-purpose remedy that can be used on various species. The two-tube format is convenient for those who need to treat multiple animals or want to keep one tube in the barn and another in a travel kit. The product is also relatively affordable compared to some veterinary-prescribed ointments, which often cost more per ounce.
However, there are clear limitations. The strong odor can be off-putting for both the animal and the owner, and it lingers for hours after application. The grease stains fabric and bedding easily, so it’s not ideal for indoor use without careful management. Additionally, while Nu-Stock can help with superficial issues, it is not a substitute for veterinary care for deep wounds, infections, or systemic problems. Some animals may also have a sensitivity to pine tar, causing further irritation rather than relief.
Compared to products like Desitin (zinc oxide cream) or generic antibiotic ointments, Nu-Stock offers a different mechanism. Desitin is mainly for moisture protection, while antibiotic creams target bacterial infections specifically. Nu-Stock’s drying and antiseptic properties make it more similar to traditional ichthammol or drawing salves, but with a stronger focus on fungal and parasitic issues like ringworm or mange. It’s not as gentle as hydrocortisone creams for allergic reactions, nor as potent as prescription antifungals for severe cases.
This product is suitable for owners who are comfortable with a messy, old-school approach to minor skin and hoof problems. It works best when the issue is caught early and the animal doesn’t have sensitive skin or a tendency to lick excessively. It is not suitable for those who prefer odorless, quick-drying treatments, or for animals with open wounds that require sterile care. It also isn’t ideal for owners who need a product that won’t stain their home or gear, as the grease can be persistent.
Overall, Pierce’s All Purpose Nu-Stock is a functional, no-frills option for basic animal skin and hoof maintenance. It has a loyal following for a reason, but it’s not a miracle cure. For someone dealing with a stubborn patch of rain rot on a horse or a dry heel crack, it may be worth trying. For a dog with a weeping hot spot, you might want to consult a vet first, as the tar could trap moisture or cause more licking. As with any topical, a patch test on a small area is wise before full application.
