Can Dogs Eat Onion Powder?

Onion powder carries all the same risks as fresh onion, just in a much more concentrated and easy-to-miss form, since it's a standard ingredient in stock cubes, gravy granules, crisps, and countless processed and takeaway foods. Because it's so widely used, a dog can end up with meaningful cumulative exposure just from being given table scraps or leftovers regularly, even if no single meal seemed like a large amount of onion. The toxic effect on red blood cells builds up over time rather than causing an immediate reaction, so symptoms like pale gums or unusual tiredness can take a couple of days to show up after the exposure. Reading ingredient labels on gravies, stocks, and seasoned foods before sharing them with your dog is the most practical way to avoid this one.
