Drooling, abdominal pain, vomiting, diarrhea, and weakness.
The toxic compounds in leeks can cause significant blood cell damage. Seek veterinary care promptly if your dog has consumed this plant.
Take the leek away and try to estimate how much was eaten and when. Bring the food packaging or a sample if possible. Do not induce vomiting at home — your vet or poison control will direct decontamination based on the dose and timing.
First-day signs are GI: drooling, oral irritation, abdominal pain, vomiting, and diarrhea. The dangerous later signs are anemia-related: lethargy, pale gums, increased heart and respiratory rate, weakness, exercise intolerance, and dark or bloody urine.
GI signs can appear within 24 hours. Hemolytic anemia is delayed and may not show up for several days; for small ingestions, signs can appear up to about a week later. Bloodwork follow-up is common.
Call a vet or ASPCA Poison Control (888-426-4435) immediately for any known ingestion of leek (including cooked dishes and seasoned scraps). Toxic dose depends on body weight, and signs can be delayed — get advice the same day.
Dogs: leeks belong to the Allium family alongside onion and garlic and are toxic to dogs. The toxic principle is N-propyl disulfide, which can cause oxidative damage to red blood cells. Japanese breeds (Akita, Shiba Inu) are more sensitive than average and need extra caution.
