You should not feed your dog any variety of watercress, unfortunately. It could lead to bouts of diarrhea and vomiting, being ultimately uncomfortable and problematic for your dog. It might also carry heavy metals or bacteria that can make your dog very ill. We will explain the potential consequences in this article.
Dogs Shouldn’t Eat Watercress

If your dog consumed watercress, you should contact poison control or your veterinary office for guidance. Generally, it causes mild side effects that will pass at home. However, if your dog ate large quantities, it could lead to a vet visit for further treatment.
What Is Watercress Exactly?
Watercress is a dark leafy green that offers a wide range of health benefits to humans. Watercress easily grows in alkaline waters and spring runs. It can easily grow in most North American areas.
Many people can grow local watercress, though it is often bought from grocery stores in the produce section. You can use this plant to spruce up salads and several other dishes. However, these same benefits do not extend to our canine companions.
All forms of cress, including American cress, winter cress, and watercress are toxic to dogs. Since watercress has a bitter, peppery taste, most dogs will have no interest in this plant. On the rare occasion that your dog does, you should keep it from their reach.
Risks Associated with Watercress Consumption
If your dog consumes watercress in any quantity, it can have an impact on their health. Some of these issues will pass in a few days, while others require veterinary intervention, such as medications or treatments.
Gastrointestinal Upset

Usually, these signs go away on their own. However, if your dog seems to be getting sicker or shows other signs of distress, it could be more serious than an upset stomach.
Contracting Bacteria or Parasites
If you feed your dog watercress that has grown wild in nature, they can contract several bacterial and parasitic infections. Usually, with proper washing, most bacteria can be avoided, but it’s a prime environment for certain germs to thrive.
Liver Fluke
Watercress can carry a parasite called liver fluke. Liver fluke is very rare in the United States. Most infections occur in Europe, Asia, Africa, and South America.
