Why Dogs Can't Eat Rhubarb: Risks and What to Do If Ingested

Rhubarb is a popular plant used in pies, jams, and other dishes, but while it may be a delicious treat for humans, it poses serious health risks to dogs. If a dog consumes rhubarb, it can lead to poisoning and severe health complications. This article explores why rhubarb is dangerous for dogs, the associated health risks, symptoms of poisoning, and what to do if your dog ingests rhubarb.

Why Is Rhubarb Toxic to Dogs?

Rhubarb contains oxalates, which are naturally occurring compounds that can be highly toxic to dogs. These compounds are found in high concentrations in rhubarb leaves and stems. When ingested, oxalates bind with calcium in the body, leading to a dangerous drop in calcium levels (hypocalcemia) and the formation of insoluble calcium oxalate crystals, which can cause kidney damage.

Additionally, rhubarb contains anthraquinones, which can lead to gastrointestinal distress, causing vomiting and diarrhea. The combination of these toxic compounds makes rhubarb highly unsafe for canine consumption.

Health Risks of Rhubarb Ingestion in Dogs

1. Hypocalcemia (Low Calcium Levels)

• Oxalates in rhubarb can cause a severe drop in calcium levels, leading to muscle tremors, weakness, and seizures.

2. Kidney Damage and Stones

• Oxalates contribute to the formation of kidney stones and may cause acute kidney failure if consumed in large amounts.

3. Gastrointestinal Issues

• Anthraquinones in rhubarb can lead to vomiting, diarrhea, drooling, and stomach pain.

4. Neurological and Cardiovascular Issues

• Severe poisoning can lead to irregular heartbeats, difficulty breathing, and even convulsions.

How to Prevent Rhubarb Poisoning in Dogs

• Keep rhubarb plants out of reach in your garden or home.
• Dispose of rhubarb leaves properly to prevent accidental ingestion.
• Educate family members about the dangers of feeding rhubarb to dogs.
• Choose dog-safe treats instead of offering any human foods that may be toxic.

Conclusion

Rhubarb is highly toxic to dogs due to its oxalate content, which can cause hypocalcemia, kidney damage, and severe gastrointestinal distress. If your dog ingests rhubarb, immediate action is crucial. Contact a veterinarian right away and monitor for symptoms of poisoning. Prevention is the best way to keep your furry friend safe, so ensure that rhubarb is kept well out of reach.
