Toxicity Risk Level
Expert Tip
Garlic is roughly 5 times more toxic than onions. Raw, cooked, dehydrated, or powdered plants in the Allium family are all toxic to dogs and can cause hemolytic anemia.
Calculation Methodology & Details
Formula
Toxicity generally begins when a dog consumes more than 0.5% of their body weight in onions at once. Garlic is computed at 5 times the toxicity of fresh onion, and powder is concentrated at 10 times the toxicity.

How to Compute Onion Toxicity Risk: Step-by-Step
Assess risk thresholds using this clinical guideline:
Determine Ingested Weight
Weigh or estimate the portion eaten. Convert ounces to grams if necessary (1 oz = 28.35 g).
Calculate Onion Equivalence
Multiply by 5 for garlic, or 10 for dehydrated powders to get the equivalent fresh onion mass.
Check the 0.5% Threshold
Compare equivalent grams with the dog's weight. If equivalent mass exceeds 5g per kg of body weight, toxicity is highly probable.
