Can dogs eat chia seeds?

Chia seeds can absorb around 10 to 12 times their weight in water. When eaten dry, they draw moisture from the mouth and gut and swell into a sticky gel. In people, a spoonful of dry seeds followed by water has caused the seeds to lodge in the esophagus. Dogs gulp food, which makes that kind of problem more likely.

Soak the seeds in water for at least 15 to 20 minutes, until they form a gel, before mixing them into food.

Chia is dense in calories and fiber. As a rough guide, measured before soaking: a quarter of a teaspoon for dogs under 10 kg (22 lb), half a teaspoon for dogs of 10 to 25 kg (22 to 55 lb), and up to a teaspoon for larger dogs. A few times a week is plenty.

Larger amounts can cause gas, bloating and loose stools.

Chia contains fiber and alpha-linolenic acid (ALA), a plant omega-3. Dogs convert ALA into the long-chain omega-3s EPA and DHA only inefficiently, so chia is not a substitute for fish oil if your vet has recommended omega-3 support. It is simply an optional extra.

Chia puddings made for people often contain sugar, honey, chocolate, coconut milk or sweeteners, sometimes including xylitol. Chia energy bars may include raisins or nuts. Plain soaked seeds are the only version to share.

Chia is not for dogs with a history of swallowing problems, megaesophagus, digestive disease or blockages, unless their vet approves. For them, the swelling that makes chia filling for people is a real hazard.
