Do not offer watercress raw or cooked. Remove it from shared plates and choose pet-safe greens instead. Contact a veterinarian if ingestion is followed by drooling, vomiting, or diarrhea.
Watercress (Nasturtium officinale) is a peppery aquatic leafy green with small rounded leaves and hollow stems, grown in cool running water. Used in soups, sandwiches, and garnish mixes.
Contains mustard-oil compounds that may irritate the mouth and GI tract. Mixed spring greens often include watercress, so exposure may occur from shared salads. Garden beds near ponds and streams create additional access.
Sold with roots in hydroponic packs. Green juices and herb blends may list it among mixed ingredients. Bagged salad kits may hide watercress sprigs among other greens.
