Is cattail poisonous to dogs

Cattails are generally not considered poisonous to dogs. However, while they are not toxic, ingesting large amounts of cattails may lead to gastrointestinal upset, such as vomiting or diarrhea. It's best to monitor your dog and discourage them from eating any plants, including cattails, to avoid potential health issues. If you suspect your dog has ingested a large quantity, consult your veterinarian.
