There are a variety of beans that are toxic to dogs, including:
- Lima beans
- Kidney beans
- Navy beans
- Pinto beans
These types of beans contain a toxin called phytohemagglutinin, which can cause gastrointestinal distress in dogs. Symptoms of toxicity include vomiting, diarrhea, and abdominal pain. In severe cases, the toxin can lead to red blood cell damage and death. If your dog has eaten any type of bean, it's important to contact your veterinarian immediately.
