Dog Onion Toxicity Calculator
Calculate the potential toxicity of onions to dogs based on their weight and the amount consumed.
What is the Dog Onion Toxicity Calculator & How does it work?
Onions contain compounds called thiosulfinates, which can be toxic to dogs. The severity of the toxicity depends on the dog’s weight and the amount of onion ingested.
The general guideline is that onions are considered toxic if a dog consumes more than 0.5% of its body weight in onions over a period of 1-2 days. For example, a 10-pound dog should not consume more than half an onion (approximately 45 grams) in this time frame.
Toxicity Level = frac{Amount of Onions Consumed}{Dog’s Weight} times 100
Toxicity Level (%) = AOC (Amount of Onions Consumed) / DW (Dog’s Weight) * 100
