Annual caraway is poisonous to dogs, cats, and horses. Whether they graze on a fresh plant, or manage to find some dried seeds in the kitchen, all parts of the plant contain an essential oil with toxic principles. Carvone is one in particular that causes thinning of the blood, while limonene causes skin and respiratory irritation. Animals who consume annual caraway experience a wide range of symptoms. Gastrointestinal irritation in the form of vomiting and diarrhea is common, as are neurological issues, such as dizziness and drooling. Muscle tremors and seizures may be witnessed too, and the animal might also have difficulty breathing. Even if a dog, cat, or horse simply touches a fresh annual caraway, the essential oils within the plant will cause skin irritations. If you think that your pet has consumed the plant, seek veterinary advice immediately. Unlike with many other toxins, inducing vomiting can exacerbate the symptoms of annual caraway poisoning, making other treatment options vital. Make sure that you prevent your pet from having access to fresh plants in the future, and keep any dried seeds you use in the kitchen well out of reach.
