Can dogs eat cooked dishes and leftovers? Caution
Caution. Fried rice, noodles, curry, burgers and many leftovers are often cooked with onion, garlic or shallots, which harm dogs even when cooked.
If your dog ate or touched this, call your vet or a pet poison line now
United States
Poison lines in other countries: United Kingdom, Australia, Canada, New Zealand
What to do now
- Call your vet or a pet poison line now if the dish had onion, garlic, shallots or chives, or your dog ate a lot.
- Note what was eaten, roughly how much, and when.
- Take away the rest, including any bones or skewers.
- Watch for weakness, pale gums or red urine over the next several days.
Don't
- Don't make your dog vomit unless a vet tells you to.
- Don't share food seasoned with onion or garlic, even a little.
How to give it safely
Set aside a plain portion of cooked meat or rice before any onion, garlic, sauce or seasoning goes in.
Signs to watch for
- Vomiting
- Diarrhea
- Weakness
- Pale gums
- Red-colored urine
When signs appear: Anemia from onion or garlic usually shows 3-5 days later
Why
Onion, garlic, shallots and chives damage red blood cells in every form: raw, cooked, dried or powdered. Powders and dry soup or seasoning mixes are the most concentrated. Leftovers can also hide cooked bones or skewers.
