Tuna ice cube treats for dogs (and cats)
Occasionally — tiny amounts
A strong-smelling reward for cats and some dogs. Mercury and salt mean this stays rare.
Recipe status: not yet tested in our kitchen. Written from common treat guidance (see Sources below). We’ll add our own photos and notes after we make it.
Treat only — not a complete diet. Homemade snacks do not replace a balanced commercial or veterinary diet. Because of mercury, keep tuna treats rare. Ask your vet if your pet has kidney disease or is on a prescription diet.
Ingredients
- 1 can (142 g / 5 oz drained) water-packed tuna, no salt added
- 120 ml (1/2 cup) water
- Ice tray with 8 cavities
Steps
Check the can: water, tuna, maybe vitamin — no salt, oil, onion, or garlic.
Flake tuna; stir in water.
Fill 8 cubes evenly.
Freeze solid (~3 hours).
Chip off a small piece for a serving; do not thaw a whole cube for a tiny cat.
Calorie estimate (label as estimate): Tuna ≈ 1.1 kcal/g (NC State). One cube ≈ 15–20 kcal estimate. Often serve 1/4–1/2 cube.
Estimates use rough USDA-style values for plain foods and will vary by brand. Put your piece calories into the dog calorie calculator and keep snacks near 10% of daily calories (WSAVA / AAHA guidance).
Storage
Freeze up to 3 weeks. Thawed leftovers: refrigerate and use within 24 hours or discard.
Dogs vs cats
Cats: a pea-to-blueberry size chip is plenty. Dogs: still occasional because of mercury — not a daily protein source. This is a treat, not a meal replacement.
