Immediately call your veterinarian or an animal poison control center. Provide them with the amount of nitroglycerin ingested, if known, and your dog’s weight and breed. Time is of the essence.
Assessing Your Dog’s Condition
Observe your dog closely for symptoms such as low blood pressure (weak pulse, pale gums), rapid breathing, increased heart rate, collapse, or vomiting. Note the time of ingestion and any changes in your dog’s behavior or physical state. This information will help your veterinarian provide the best possible treatment.
Follow your veterinarian’s or poison control center’s instructions carefully. They may recommend inducing vomiting or administering activated charcoal, but only do so if explicitly instructed. Never attempt to treat your dog without professional guidance. Prompt, appropriate veterinary care significantly improves your dog’s chances of recovery.
Transporting Your Dog
If instructed to transport your dog to a veterinary clinic, do so carefully and as quickly as possible. Minimize stress and keep your dog comfortable. Keep the nitroglycerin container for reference, but do not handle it unnecessarily.
