FreeStyle Lamb, Mackerel & Kelp In Broth Topper
Verified Jun 20, 2026
A high-moisture, meat-based topper for dogs, featuring lamb and mackerel in broth with added kelp. It’s designed to be used alongside a complete and balanced dog food to boost protein, flavor, and hydration. This can work well for dogs who need extra encouragement to eat or enjoy more variety in their meals.
Nutritionally, this is a simple, high-quality topper built around real lamb and mackerel with very few extra ingredients. It’s rich in animal protein for a wet product and provides extra moisture, which many dogs can benefit from. Because it is not a complete and balanced diet, it should only be used alongside a regular, balanced dog food rather than as the main meal.

KibbleLab Review
Strengths
- Very short, transparent ingredient list with lamb and mackerel as the primary components, providing high-quality animal protein.
- High moisture content can help support hydration, especially for dogs that don’t drink a lot of water or eat only dry food.
- Free from corn, wheat, soy, and artificial flavors or preservatives, which some sensitive dogs do better without.
- Moderate protein and fat levels for a topper, making it a flavorful add-on without being extremely rich for most dogs.
Considerations
- This product is not complete and balanced and is labeled for intermittent or supplemental feeding only, so it should not replace a regular dog food.
- Contains lamb and fish, which are common allergens for some dogs; it’s not a good fit if your dog reacts to either of those proteins.
- As a meat-and-broth–based topper without added vitamins and minerals, it relies entirely on the main diet to meet all of your dog’s nutrient needs.

Top 5 Ingredients Explained
01
Lamb
Lamb is commonly used in dog and cat foods as a high-quality animal protein that supplies essential amino acids, iron and B vitamins and is often chosen for its palatability or as a “novel” protein in elimination diets. It can be higher in fat and calories than some other meats and may still cause allergic reactions in sensitive animals, so owners of overweight pets or those with food sensitivities should consult a veterinarian and use proper handling/cooking practices if feeding raw or homemade lamb.
02
Lamb Broth
Lamb broth is used in pet foods and toppers primarily as a flavorful, moisture-rich base or gravy to boost palatability and hydration, and it can contribute small amounts of animal protein, amino acids, and electrolytes. Pet parents should be aware that broths can be high in sodium or fat and may contain allergens or toxic seasonings (e.g., onion, garlic, xylitol), so choose low‑sodium, pet-safe formulations and consult a veterinarian for pets with dietary restrictions or sensitive stomachs.
03
Mackerel
Mackerel is a fatty fish commonly used in pet foods as a high‑quality animal protein and a rich source of omega‑3 fatty acids (EPA and DHA), often added for flavor, palatability and healthy fats. Its omega‑3s support skin and coat condition, immune and joint health in dogs and cats, but owners should be aware of potential heavy‑metal accumulation, food sensitivities, and higher fat or sodium in some preparations, so choose properly processed, deboned sources from reputable suppliers.
04
Mackerel Broth
Mackerel broth is used in pet foods and toppers mainly as a palatant and moisture enhancer that adds savory fish flavor and can contribute small amounts of fish protein, minerals, and marine omega‑3 fatty acids (EPA/DHA), often making it particularly attractive to cats. Nutrient and sodium content can be variable, so owners should watch for fish allergies, elevated salt levels, and potential quality issues (e.g., histamine or spoilage); manufacturers control formulation to limit heavy‑metal or contaminant risks.
05
Kelp
Kelp is a dried seaweed ingredient used in dog and cat foods primarily for trace minerals (notably iodine), vitamins, fiber, and natural flavor rather than as a significant protein or energy source. It can support skin, coat and general micronutrient intake, but iodine levels are highly variable and excessive iodine or contaminants from poorly sourced kelp can affect thyroid function or introduce heavy metals, so pets with thyroid disease should have intake discussed with their veterinarian and products should come from reputable suppliers.
