Can dogs eat cinnamon?
Ask your vet about your own pet. This page is general information from the sources below.
Cinnamon is only for small amounts, or in certain forms, for dogs. Pet Poison Helpline says cinnamon is generally well tolerated by pets. Eating more than about a teaspoon of the powder can cause low blood sugar, liver problems, vomiting and diarrhea. The powder can also be breathed in and irritate the lungs. A tiny sprinkle baked into food is not the worry.

Why
Pet Poison Helpline says cinnamon is generally well tolerated by pets. Eating more than about a teaspoon of the powder can cause low blood sugar, liver problems, vomiting and diarrhea. The powder can also be breathed in and irritate the lungs.
How to serve it
A tiny sprinkle baked into food is not the worry. Do not let a dog eat the powder from the jar.
Good to know
The form matters most: Pet Poison Helpline says the essential oil is the risky one, because only a small amount can cause harm.
Watch for: Cinnamon oil in diffusers and cooking products, and cinnamon sticks left in drinks.
Already ate it?
If your pet ate a lot, or you are worried, call your vet. Say what was eaten, how much and when, and have your pet's weight ready.

For the children
"Cinnamon is only a tiny treat for dogs, and only a grown-up decides how much."
A job: Be the label reader. Before a grown-up shares any food with the dog, check this page, and ask a grown-up if the food is not on it.
