Frequently asked questions
Is cooked onion safe for French Bulldogs?
No — cooking does not eliminate the toxic compounds. All forms of onion are equally dangerous.
How much onion is toxic for a dog?
As little as 0.5% of body weight can cause toxicity. For a 10kg French Bulldog, that is just 50g — less than a small onion.
What are signs of onion poisoning in dogs?
Lethargy, weakness, reduced appetite, pale or yellowish gums, reddish urine, and laboured breathing. These can appear 1–3 days after eating onion.
Is onion powder more dangerous than raw onion for dogs?
Yes — onion powder is more concentrated. Smaller amounts can cause toxicity compared to raw onion.
