Lickable Treat Tuna Purée Recipe

Fish broth is used in pet food primarily as a flavor and moisture enhancer, providing modest amounts of fish-derived protein, amino acids, minerals and sometimes trace omega‑3s but not serving as a primary source of complete nutrition. It can improve hydration and entice picky, senior, or ill dogs and cats to eat, but caregivers should watch for high sodium, added seasonings (especially onion or garlic), potential fish allergies, and variable quality depending on processing.

Tuna fillet is commonly used in pet foods and treats as a highly palatable, lean animal protein that provides EPA/DHA omega‑3 fatty acids, B vitamins (notably B12) and minerals like selenium, supporting skin and coat condition, cognitive health and general protein needs for both dogs and cats. It should be fed in moderation and within a balanced diet because frequent large servings—especially canned tuna—can contribute to mercury and excess sodium exposure, and raw tuna may carry parasites or enzymes that affect thiamine; prefer cooked, boneless, unsalted preparations and consult your veterinarian for long‑term use.

Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.

Sunflower oil is used in pet foods as a concentrated fat source to increase energy density, palatability and supply linoleic acid (an essential omega‑6) that helps maintain healthy skin and coat. It is beneficial for dogs and cats but is high in omega‑6 and low in omega‑3—so formulas should balance fatty acids to avoid an inflammatory imbalance; it is calorie‑dense (important for weight control and pancreatitis-prone animals) and may require antioxidants or high‑oleic formulations for better shelf stability.

Guar gum is a soluble plant-derived fiber commonly used in pet foods as a thickener, stabilizer and emulsifier to improve texture, moisture retention and prevent separation in wet foods, gravies and coatings. It provides little nutritional value beyond soluble fiber—which can help stool consistency and modestly slow digestion—but excessive amounts may cause gastrointestinal upset or affect nutrient absorption, so it is used at controlled low levels and is generally considered safe for most dogs and cats.
