ORIJEN SENIOR DOG DRY FOOD (All BREEDS)

• ORIJEN Senior is a dry kibble formulated for senior dogs, all breeds. 

• It is designed as a “Biologically Appropriate” diet — mimicking what dogs would naturally eat in the wild (lots of fresh or raw animal-based ingredients, organs, bone, etc.). 

Key Features / Ingredients

1. High Animal Protein Content

   • Around 85% quality poultry and fish ingredients (fresh or raw) by unprocessed weight. 

   • First 5 ingredients typically are fresh or raw chicken, turkey, wild-caught fish, eggs, etc. 

2. WholePrey Philosophy

   • Uses not just muscle meat, but also organs, cartilage, bone etc. — to deliver natural vitamins, minerals, fats and other nutrients that are part of a more complete diet. 

3. Grain-Free

   • There are no grains (wheat, corn, soy etc.) in the formula. This is often helpful for dogs with sensitivities toward grains. 

4. Freeze-Dried Liver Coating

   • To enhance flavor (palatability) by using freeze-dried liver coating. Helps to make it more attractive to dogs, especially picky eaters. 

5. Joint & Weight Support

   • Nutrient profile aims to help maintain lean muscle mass, support healthy joints, and help manage weight. ORIJEN has included things like glucosamine, chondroitin (or similar joint‐supporting nutrients) for senior dogs. 

6. Omega Fatty Acids, Vitamins, Antioxidants

   • Provides omega-3 and omega-6 fatty acids for skin, coat, immune and brain health.

   • Also roughly balanced minerals (calcium, phosphorus etc.), vitamin content, naturally occurring as much as possible via whole ingredients. 

Nutritional / Analytical Breakdown

Here are typical numbers (these may vary slightly by region):

• Metabolizable Energy: Approx 3,700 kcal/kg (or thereabouts) depending on region; for example UK version gives about 3,710 kcal/kg. Orijen Pet Foods+1

Benefits for Senior Dogs

• Helps maintain muscle mass in older dogs, since protein density is high.

• Supports joint health via natural cartilage, bone, plus glucosamine/chondroitin.

• Helps in weight management, since fat and calorie levels are controlled (not excessively high, but enough to maintain condition).

• Supports immune, skin & coat health via good fats (omega 3/6), antioxidants from fruits/veggies/herbs.

• No grain fillers which can reduce risks of intolerance for some dogs.

• Enhanced flavor (freeze-dried liver etc.) can help older dogs often becoming picky.

Things to Watch / Consider

• Some dogs may not tolerate high protein / multiple novel meats or legumes well — switching gradually helps.

• Grain-free diets have been under scrutiny in some contexts (e.g. possible links to certain heart issues) though ORIJEN is generally well-regarded; still good to monitor your dog’s health and perhaps discuss with a vet.

• Cost: premium ingredients and complex formulation mean ORIJEN is on the higher price side.

• Portion control is important — since older dogs often have lower activity, the high nutritional density means over-feeding can lead to weight gain.
