Ingredients
  

Protein
  • 8 oz (about 225 g) Whitefish fillets, boneless and skin removed (e.g., cod, haddock)
  • 1 large Large egg
Vegetables & Fruit
  • 1 medium (about 150 g) Russet or Yukon potato, cooked and mashed
  • 1/3 cup Carrot, finely grated
  • 1/4 cup Frozen peas, thawed
  • 1/4 cup Plain canned pumpkin puree (not pie filling)
Binders & Grains
  • 1/2 cup Rolled oats, lightly ground
  • 2 tablespoons Whole wheat flour (optional, helps bind)
Seasoning & Oil
  • 1 teaspoon Extra-virgin olive oil
  • 1 teaspoon Fresh parsley, finely chopped
  • 2 tablespoons Cold water (to adjust mixture consistency)

Equipment

  • Oven
  • Baking sheet
  • Parchment paper
  • Mixing bowl
  • Measuring cups and spoons
  • Fork (for flaking and mashing)
  • Mixing spoon
  • Knife
  • Cutting board
  • Grater

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper and set aside.
  2. Cook the potato until tender (boil or microwave). Drain and mash thoroughly; set aside to cool slightly.
  3. Place the whitefish fillets on a small parchment-lined baking sheet and bake in the preheated oven for 10–12 minutes, or until the fish is opaque and flakes easily with a fork. Carefully check for and remove any remaining bones; discard bones safely.
Mixing & Shaping
  1. In a large mixing bowl, flake the cooked whitefish with a fork until small pieces remain. Add the mashed potato, grated carrot, thawed peas, pumpkin puree and the egg.
  2. Stir in the ground oats, whole wheat flour, chopped parsley and olive oil. Add 1–2 tablespoons cold water as needed to achieve a soft, moldable mixture — not runny.
  3. Using a tablespoon or small cookie scoop, form the mixture into 12 small patties (about 2 tablespoons each) and place them on the prepared baking sheet, spacing evenly.
Baking & Cooling
  1. Bake the patties for 16–20 minutes, until set and lightly golden at the edges. Remove from the oven and allow to cool completely on a wire rack before serving.
  2. Store cooled patties in an airtight container in the refrigerator for up to 3 days or freeze in a single layer on a tray, then transfer to a freezer-safe bag for up to 3 months. Thaw in the refrigerator before serving.

Notes

Storage & Reheating

Refrigerate baked patties in an airtight container for up to 3 days. For longer storage, freeze patties on a tray until solid and then transfer to a freezer-safe bag for up to 3 months. Reheat briefly to room temperature or warm (microwave briefly or in a low oven) and always check temperature before giving to your dog.

Variations

Swap sweet potato for regular potato (equal volume) or use cooked white fish like pollock or haddock. For a grain-free option, replace the oats with cooked quinoa or a small amount of canned lentils, and omit the whole wheat flour.

FAQs

Is this recipe suitable for all dog sizes and ages?
This recipe is intended as an occasional treat or small meal for adult dogs of all sizes. Adjust portion sizes (see portion-control FAQ) and consult your veterinarian before serving to puppies under 6 months or senior dogs with special needs.
What if my dog has allergies?
If your dog has a known allergy to fish, eggs, wheat or pumpkin, do not feed this recipe. Consider safe substitutions in the Variations section and introduce any new ingredient slowly while monitoring for reactions.
How often can I feed these whitefish patties?
Feed these patties as an occasional meal or treat — for most dogs once or twice per week is appropriate. They are not intended to replace a complete balanced diet.
Can I substitute other ingredients if I don’t have them?
Yes. Sweet potato may replace regular potato (equal volume). Use another mild, deboned white fish if needed. For grain-free, substitute cooked quinoa for oats. Avoid adding salt, onions, garlic, or other toxic ingredients.
How should I store leftovers safely?
Keep leftovers refrigerated in an airtight container for up to 3 days. Freeze for longer storage (up to 3 months). Thaw frozen patties in the refrigerator, and discard any patties left at room temperature for more than two hours.
How much should I give my dog per serving?
Portion control depends on your dog’s size and daily calorie needs. As a guideline: small dogs (5–15 lb) 1–2 tablespoons, medium dogs (15–40 lb) 2–4 tablespoons, large dogs (40+ lb) 4–6 tablespoons as an occasional meal or treat. Adjust based on activity level and consult your vet for specific guidance.
Any tips to make preparation easier?
Ensure the fish is fully cooked and carefully check for bones. Use cooled mashed potato to avoid overcooking the egg in the mix. Lightly grind the oats for a smoother texture and use a tablespoon or small scoop for uniform patties.
When should I NOT feed this recipe?
Do not feed if your dog has a diagnosed fish, egg or grain allergy, or if your veterinarian has advised against these ingredients for a medical reason. Also avoid if the dog has a history of sudden food sensitivities until cleared by a vet.
Should I consult my veterinarian before offering this to my dog?
Yes. Consult your veterinarian if your dog has health conditions, dietary restrictions, or is on a special therapeutic diet before serving new homemade recipes.
How should I introduce this new food?
Offer a small piece (a few teaspoons) at first and wait 24 hours while watching for any digestive upset or allergic reaction. If all is well, gradually increase to a full portion over several days.

This Low-Sodium Whitefish & Potato Dog Recipe is intended as an occasional treat or meal and is not a complete diet. Introduce new foods gradually and monitor your dog for any reactions.
