Can dogs eat chives or leeks?
No, toxic No. Chives and leeks belong to the same family as onions and garlic and can damage a dog's red blood cells.
Why
Chives and leeks are Allium plants, like onion and garlic, and carry the same sulphur compounds that damage red blood cells and can lead to anaemia. The MSD Veterinary Manual notes that garlic and onion cause most recorded cases, but PDSA and RSPCA say every part of these plants is toxic to dogs, cooked or dried, and some dogs are more sensitive than others. Watch for them in sauces, soups and flavoured cheeses.
Signs to watch for
- Vomiting and diarrhoea
- Reduced appetite and a sore tummy
- Lethargy and weakness
- Pale gums
- Fast breathing or a fast heart rate
- Red or dark urine
- Collapse
If your dog ate chives and leeks
Call your vet as soon as possible, even if your dog seems well: signs of anaemia usually take a few days. If it was within about four hours, your vet may make your dog sick and give activated charcoal. Tell them roughly how much was eaten and whether it was raw, cooked or powdered. Do not try to make your dog sick yourself.
If your dog has eaten something toxic
Call your vet or the nearest emergency vet now. Do not wait for signs, and do not make your dog sick unless a vet tells you to. Take the packet with you.
