My dog chewed on a leek from my vegetable garden, how serious is this?

Short answer

This is very serious; leeks are toxic to dogs, just like onions and garlic. They contain compounds that damage red blood cells, which can lead to life-threatening anemia. Symptoms like weakness, pale gums, and red-tinged urine may not appear for a few days. Do not wait for signs to show. Contact your veterinarian or the ASPCA Animal Poison Control Center at 888-426-4435 right away, and be ready to tell them your dog's weight and about how much was eaten.
