Onion Toxicity in Dogs

Onions contain a compound called N-propyl disulfide that can damage the red blood cells of dogs and cause a condition called hemolytic anemia.

The amount of onion that can cause toxicity depends on the size and breed of the dog, as well as the type and form of onion. Generally, a dose of 0.5% of the dog’s body weight can be toxic. For example, a 10 kg dog can get sick from eating 50 grams of onion. However, some breeds, such as Akita and Shiba Inu, are more sensitive to onion toxicity and can get sick from smaller doses.

• Giving fluids and oxygen to support the circulation and respiration
• Giving blood transfusions to replace the damaged red blood cells
• Giving antibiotics to prevent infections
• Monitoring the dog’s vital signs and blood parameters until recovery

The prognosis of onion poisoning depends on the amount of onion ingested, the time elapsed since ingestion, and the severity of the symptoms. Some dogs may recover within a few days, while others may need weeks or months of treatment. In some cases, onion poisoning can be fatal.
