Step-by-Step Breakdown

1. Values used:

2. Dog weight = 15

3. Onion eaten = 30

5. Dose = Onion eaten / Dog weight = 30 / 15 = 2g/kg

The math behind it

dose (g/kg) = onion grams ÷ weight (kg). Toxicity is generally seen around 5 g/kg (about 0.5% of body weight), but smaller amounts over time also harm.

Worked Example

15 kg dog, 30 g onion → 2 g/kg (monitor; still call a vet).
