Can Dogs Eat Rhubarb?

No, dogs should not eat rhubarb. Rhubarb contains oxalic acid, which can be toxic to dogs if ingested in large quantities. Oxalic acid can affect the kidneys and lead to kidney damage or failure in dogs. Even small amounts of rhubarb can cause gastrointestinal upset, including symptoms like drooling, vomiting, diarrhea, and abdominal pain.

It's essential to keep rhubarb and any rhubarb-containing dishes out of reach of your dog and ensure that they do not have access to it. If you suspect your dog has ingested rhubarb or is showing any signs of distress after consuming it, you should contact your veterinarian immediately for guidance and treatment. It's always better to be cautious when it comes to sharing human foods with your pets and to stick to safe, dog-friendly treats and foods.

Here are some more details about why rhubarb is harmful to dogs:

Oxalic Acid Content: Rhubarb leaves, in particular, contain a high concentration of oxalic acid. While the stalks (the edible part) also contain some oxalic acid, it is less concentrated. Oxalic acid can bind to calcium in the body, forming crystals or stones that can lead to kidney problems and other health issues in dogs.

Kidney Damage: When a dog ingests rhubarb, the oxalic acid can irritate the mucous membranes of the mouth and gastrointestinal tract, causing symptoms like drooling, vomiting, and diarrhea. However, the more significant concern is the potential for oxalic acid to cause kidney damage. If enough oxalic acid is absorbed into the bloodstream, it can overwhelm the kidneys and lead to acute kidney injury or failure.

Toxicity Symptoms: Signs of rhubarb toxicity in dogs may include:

• Drooling
• Vomiting
• Diarrhea, possibly with blood
• Abdominal pain
• Lethargy
• Increased thirst and urination (early signs of kidney damage)
• Decreased or no urine production (advanced kidney damage)

If you suspect your dog has ingested rhubarb or is displaying any of these symptoms after consuming it, seek immediate veterinary attention. The veterinarian may induce vomiting if the ingestion was recent or administer treatments to support kidney function and manage symptoms.

To prevent accidental ingestion, it's crucial to keep rhubarb plants and dishes made with rhubarb out of your dog's reach. Also, educate family members and guests about the dangers of feeding rhubarb to dogs. Stick to safe and dog-friendly treats and foods to ensure the well-being of your canine companion.
