The Animal Health International 12378158 Cattle Parasiticide (1% Ivermectin) is specifically formulated for cattle and swine, and its use on dogs is off-label and not recommended without veterinary guidance. While ivermectin is sometimes prescribed for dogs, the dosage and formulation must be carefully adjusted based on the dog's weight, breed, and health condition. Administering this product orally or in a diluted form to dogs without professional advice could lead to toxicity or severe side effects, especially in breeds like Collies, Australian Shepherds, and Shelties, which are more sensitive to ivermectin. For your dog's safety, consult a veterinarian before considering any off-label use. Let me know if you'd like help finding more information or alternatives!
