FreeStyle Mackerel, Chicken & Mussel In Broth Topper

Verified Aug 22, 2026

Dog · Topper All Breed Sizes

This is a high-moisture, shredded topper for dogs featuring mackerel, chicken, and mussel in broth as simple, animal-based ingredients. It’s designed to be served alongside a complete and balanced dog food to add extra protein variety, flavor, and hydration. The very short ingredient list makes it a straightforward option for owners who want to boost palatability without a lot of extras.

Strong Choice

Nutritionally, this is a simple, animal-protein–only topper that can work very well for dogs who need more flavor, moisture, or variety added to their regular balanced diet. The short ingredient list centered on named fish, chicken, and mussel is a nice, transparent approach, and the moderate calorie content per pouch makes it easy to add without drastically changing total intake. It does contain both fish and chicken, so it won’t be appropriate for dogs who need to avoid those proteins, and it should never be used as the sole diet since it’s not complete and balanced.

Nutritional Perspective

KibbleLab Review

Strengths

  • Very short, straightforward ingredient list with named animal proteins (mackerel, chicken, mussel) and broths only.
  • High moisture (87%) helps support hydration and can make meals more appealing for dogs that are picky or don’t drink much water.
  • Low fat and modest calorie content per pouch (about 44 kcal) allow it to be added to most dogs’ meals without a large impact on daily calories.
  • Grain-, corn-, and soy-free formula may suit dogs whose owners prefer to avoid those ingredients for personal or dietary reasons.

Considerations

  • Labeled as a complementary food only and is not complete and balanced, so it must be fed alongside a nutritionally complete main diet, not as the only food.
  • Contains both fish (mackerel, mussel) and chicken, which are common protein allergens, so it’s not a good choice for dogs with known allergies to these ingredients.
  • Very low fat content may not be ideal if you’re specifically looking to add extra dietary fat for dogs that need higher energy density from toppers.

Top 5 Ingredients Explained

01
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.

02
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.
03
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.

04
Chicken Broth
Chicken broth is commonly used in pet foods and toppers as a flavorful liquid base or gravy to improve palatability and add moisture, providing modest amounts of soluble protein, electrolytes and minerals. It can help encourage eating and increase hydration, but owners should choose low‑sodium, onion‑ and garlic‑free formulations (or make homemade broth), since commercial broths may contain excessive salt, seasonings or additives that are unsafe or unsuitable for dogs and cats.
05
Mussel
Mussel, especially green‑lipped mussel, is used in pet foods and supplements as a high‑quality animal protein and a natural source of omega‑3 fatty acids plus glucosamine and chondroitin, which can help support joint health and reduce inflammation. It also supplies minerals and B vitamins and can enhance palatability, but owners should be aware of potential shellfish allergies, variability in nutrient content depending on processing and sourcing, and that it should complement a balanced diet—consult your veterinarian if your pet has food sensitivities or is on medication.
