1 teaspoon flaked
Water-packed preferred.
Medium 20–50 lb
1–2 teaspoons
No tomato sauce.
Large 50+ lb
1 tablespoon
Occasional topper.

Rule of thumb: treats of all kinds should stay under ~10% of daily calories.

How to prepare them

  • Choose plain sardines in water when possible.
  • Drain well; flake and remove large bones if present.
  • Skip tomato sauce, chili, and heavily salted packs.

Risks & exceptions

  • Sodium and calories add up quickly.
  • Sauced tins can include onion or spice.

Sardines are an occasional fish topper, not a daily can. Prefer water-packed and plain.

If they ate too many

Too much rich fish can upset the stomach.

  • Soft stool
  • Fishy burps

Call your vet / pet poison line if:

  • Repeated vomiting
  • A large salty tin eaten at once
