It is not recommended to administer any medication to your pet without consulting a veterinarian. The safety and effectiveness of any medication can vary depending on the species, age, weight, and health status of the animal. A veterinarian can assess your pet's condition and provide the appropriate dosage and instructions for any necessary medications. Self-medicating your pet can be dangerous and can have serious consequences. Always consult a veterinarian before giving any medications to your pet.
