Prepare the Ingredients:

1. Cook the Potatoes: Start by boiling the potatoes in a large pot with enough water to cover them. Cook for about 10-15 minutes or until they are soft and fully cooked. Drain and set them aside.
2. Prepare the Vegetables: In a separate pan, heat the olive oil over medium heat. Add the carrots, peas, and spinach (or kale). Sauté for about 5-7 minutes, until the vegetables soften slightly but remain tender.
3. Prepare the Tuna: Open the can of tuna, drain it well, and set it aside in a large mixing bowl. Make sure to remove any excess oil or water to avoid upsetting your dog’s digestion.

Combine the Ingredients:

4. Mash the Potatoes: Once the potatoes are soft and drained, mash them with a fork or potato masher until smooth. If your dog prefers a chunkier texture, you can leave some small pieces intact.
5. Mix the Tuna and Veggies: Add the sautéed vegetables to the mashed potatoes and combine them with the tuna. Mix thoroughly to ensure everything is evenly distributed. You may choose to add the egg at this stage (optional) to help bind the ingredients together.
6. Add Liquid: If the mixture seems too thick, you can add water or low-sodium chicken broth a little at a time until the consistency is suitable for your dog.
7. Add Seasoning: Sprinkle in a pinch of turmeric (optional) for anti-inflammatory benefits. You can also add a tiny pinch of salt, but be cautious not to overdo it, as too much salt can be harmful to dogs.

Cool and Serve:

8. Cool the Food: Allow the Potato, Tuna, and Vegetable Dog Food to cool completely before serving it to your dog. Hot food can burn their mouths and cause discomfort.
9. Serve: Once the food has cooled, serve it in your dog’s regular dish. You can adjust the portion size according to your dog’s size and appetite.
