Buying Guide
Lamb as a Novel Protein
Despite being increasingly common in dog food, lamb remains a useful alternative protein for dogs that have not been previously exposed to it. Lamb provides complete amino acids with excellent palatability – particularly for dogs bored with chicken-based foods.
Lamb for Allergy Management
Lamb is commonly recommended for dogs with chicken or beef allergies. However, as lamb has become more prevalent in dog food, some dogs have developed lamb allergies through repeated exposure. If your dog has been eating lamb for years, it may no longer be a ‘novel’ protein for them.
Nutritional Profile of Lamb
Lamb is moderately higher in fat than chicken or turkey, which makes it more calorie-dense. It is rich in zinc (supporting immune function and skin health), iron, B vitamins, and selenium. The higher fat content also contributes to its palatability and rich flavor.
Lamb vs. Chicken: Which Is Better?
Neither is universally better. Chicken is leaner; lamb is fattier and more calorie-dense. Lamb’s higher zinc and iron content benefits dogs with skin or immune conditions. For weight management, chicken is typically preferred. For dogs with chicken allergies or those needing a different flavor profile, lamb is an excellent choice.
Frequently Asked Questions
Is lamb good for dogs with sensitive stomachs?
Yes, lamb is generally well-tolerated by dogs with sensitive stomachs, particularly when combined with easily digestible carbohydrates like brown rice or sweet potato. Lamb-based limited ingredient diets are a common recommendation for dogs with chronic digestive issues.
Is lamb a common allergen in dogs?
Lamb allergies exist but are less common than chicken or beef allergies. However, dogs that have been eating lamb-based food for many years can develop lamb sensitivities. If your dog develops allergy symptoms on a lamb diet, consult your vet about switching to a different novel protein.
What is the best lamb dog food for large breeds?
For large breeds, look for lamb formulas that include joint-supporting ingredients like glucosamine and chondroitin, along with appropriate calorie density. Natural Balance LID Lamb and Hill’s Science Diet Lamb & Rice are suitable for large breed adults.
Can puppies eat lamb dog food?
Yes, puppies can eat lamb-based food if it is formulated for puppy growth and AAFCO-approved for that life stage. Most lamb formulas are available in adult versions; verify the formula is appropriate for puppies before feeding.
