Can Dogs Eat Pesto?

ToxicContains Garlic — Avoid

No. Traditional pesto is made with garlic as a core ingredient, alongside pine nuts and often significant oil content, and should not be shared with dogs.

Why

Garlic is a defining ingredient of traditional pesto, not an optional extra, making this a genuine Allium-family toxicity risk (see our onions & garlic page) rather than just a rich, fatty food to moderate.

Symptoms to watch for

Timing	What to expect
2–5 days	Lethargy, pale gums, dark urine — delayed signs of garlic-related anaemia

What to do if your dog ate this

Don't share pesto in any amount, given the garlic content
If a dog eats a meaningful amount of pesto, treat it as a garlic exposure and monitor for delayed anaemia signs

🚨 If this happens

Contact your nearest 24-hour emergency vet clinic immediately, or your regular vet's after-hours line. Bring packaging if you have it.
