Lamb & King Salmon Feast Freeze-Dried Dog Food
Verified Jun 17, 2026
This is a very high-protein, high-fat freeze-dried dog food made mostly from New Zealand lamb, lamb organs, ground bone, and king salmon, with small amounts of vegetables, flaxseed, and green mussel. It’s designed as a complete and balanced diet for most dogs of all ages, or as a nutrient-dense topper to boost another food. The recipe is rich in omega-3 and omega-6 fats, which can support skin, coat, and overall health, but its calorie density means portions need to be carefully measured.
Nutritionally, this is a very high-quality, meat-rich freeze-dried diet that suits dogs who do well on a high-protein, high-fat, low-carbohydrate approach. The use of lamb meat, organs, bone, and king salmon provides a wide range of amino acids and naturally occurring minerals, while flaxseed and green mussel add beneficial fatty acids. It’s best for dogs with normal activity and good metabolism whose owners are comfortable carefully measuring portions of a very calorie-dense food, and it is not intended for large-breed puppies in their rapid growth phase.

At a Glance
What "not formulated for" means
Life stages this food isn't certified complete and balanced for, based on its AAFCO statement.KibbleLab Review
Strengths
- Extremely high animal content (lamb meat, multiple lamb organs, ground bone, and king salmon) provides excellent quality protein and naturally rich mineral sources.
- Guaranteed 40% protein and 38% fat (as-fed) are very high for a dry food, giving a nutrient-dense option for dogs that tolerate richer diets well.
- Includes omega-3 sources from salmon, flaxseed, and New Zealand green mussel, which can support skin, coat, and joint health.
- Formulated to meet AAFCO nutrient profiles for all life stages except large-breed puppy growth, so it can serve as a complete and balanced diet for most dogs when fed as directed.
Considerations
- Very calorie-dense at 5,150 kcal/kg and 221 kcal per cup, so overfeeding is easy if portions are not carefully controlled, especially for smaller or less active dogs.
- The high fat level may be too rich for dogs with a history of pancreatitis, fat sensitivity, or certain gastrointestinal issues.
- Contains lamb and fish, which are common protein allergens; not appropriate for dogs with known lamb or fish allergies.
- Not suitable as the sole diet for large-breed puppies expected to reach over 70 lb as adults, due to specific growth requirements for those dogs.

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
New Zealand King Salmon
New Zealand King Salmon is used in pet foods as a high-quality, highly digestible animal protein and a concentrated source of omega‑3 fatty acids (EPA and DHA), which support healthy skin and coat, joint function, and have anti-inflammatory benefits for both dogs and cats. It is a nutritious ingredient but can be an allergen for some pets and should be properly processed to eliminate parasites/pathogens; owners should also consider sustainable sourcing and contaminant testing, and ensure the overall diet is balanced to meet species-specific needs such as adequate taurine for cats.
03
Lamb Tripe
Lamb tripe is the stomach lining of lambs commonly used in dog and cat foods as a highly palatable animal-based protein and flavor enhancer that also supplies fat, digestible amino acids, B vitamins (notably B12), iron and other trace minerals. It can provide natural digestive enzymes and, when unwashed, beneficial microbes, but its strong odor, higher fat content and risk of spoilage or pathogen contamination mean it should be properly sourced and handled, introduced gradually to avoid GI upset, and included as part of a balanced diet rather than the sole ingredient.
04
Lamb Lung
Lamb lung is an organ meat commonly used in pet foods and treats as a lean, highly palatable protein source and flavor enhancer, supplying readily digestible protein along with B vitamins, iron and other minerals that benefit both dogs and cats. It is typically safe and low in fat when properly sourced and processed (cooked or dehydrated) to eliminate pathogens, but it is not especially rich in taurine so should not be the sole ingredient in a cat’s diet; pet owners should also monitor for individual allergies and buy from reputable suppliers to reduce contamination risk.
05
Lamb Liver
Lamb liver is an organ meat used as a nutrient-dense protein and flavor enhancer in pet foods and treats, supplying concentrated vitamins (especially vitamin A and B12), iron, copper and high-quality amino acids important for both dogs and cats. It is highly palatable and can help prevent nutrient deficiencies, but should be fed in moderation because excessive liver intake can lead to vitamin A toxicity and digestive upset, and proper sourcing/handling is important to avoid foodborne pathogens.
