How much celery for your dog?
Most guides say "a few pieces". Enter your dog's weight and get the actual daily ceiling, worked out from celery's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for dogs
Celery is a crunchy, low-calorie treat that is high in fibre. Cut into small pieces to prevent choking.
Celery is a crunchy, hydrating, nearly calorie-free treat — a favorite for dogs on a diet, with a bonus reputation for freshening breath. Cats can have it too; some even enjoy the leaves.
How much is safe?
A few bite-size pieces make a great low-calorie snack, and it's hard to overdo calorie-wise. It's mostly water and fiber, so the practical limit is the stomach, not the scale.
What happens if a dog eats too much?
Lots of celery can mean loose stool from the fiber and water. The real caution is mechanical: celery is stringy, and long pieces can be a choking hazard — especially for small dogs and gulpers.
How to serve it safely
Wash, trim the leaves if your pet dislikes them, and cut into bite-size chunks across the stalk (short pieces = fewer strings). Plain only — celery with peanut butter is fine if the PB is xylitol-free and minimal.

Is celery a choking hazard?
Long stringy pieces can be, especially for small dogs. Cut it into short chunks across the stalk.
