Canine Urinary SO Aging 7+ Loaf in Sauce Wet Dog Food

Verified Jun 30, 2026

Dog · Wet Senior All Breed Sizes

This is a veterinary therapeutic wet food formulated for adult and senior dogs with urinary stone issues, particularly struvite and calcium oxalate crystals. It uses chicken, pork by-products, and liver as primary protein sources, with added cellulose for fiber and adjusted minerals to help create a urine environment less favorable to stone formation. The recipe also includes fish oil, L-carnitine, antioxidants, and targeted nutrients to support older dogs’ kidney function and overall vitality.

KibbleLab Score
8.7 out of 10

A well-designed veterinary urinary diet tailored for senior dogs, with thoughtfully adjusted minerals and ingredients to help manage and reduce certain urinary crystals while still providing complete and balanced daily nutrition. The protein comes from a mix of chicken, organ meats, and by-products, which are generally nutrient-dense, and the formula includes supportive extras like fish oil, L-carnitine, and antioxidants for aging dogs. This is most appropriate for dogs who have urinary stone issues and are under the ongoing guidance of a veterinarian.

Nutritional Perspective

KibbleLab Review

Strengths

  • Therapeutic urinary formula aimed at helping dissolve and reduce recurrence of specific urinary stones while remaining complete and balanced for adult dogs.
  • Multiple named animal protein sources (chicken, chicken liver, pork by-products, chicken by-products, pork liver) that supply essential amino acids and micronutrients, especially important in seniors.
  • Includes fish oil, taurine, L-carnitine, and antioxidant vitamins, which can be helpful for senior dogs’ overall health and vitality.
  • Wet loaf texture with moderate protein and fat and high moisture, which can support higher water intake—a key factor in urinary health.

Considerations

  • Contains chicken and pork, which are common triggers for food allergies in some dogs, so it may not suit dogs with those specific protein sensitivities.
  • This is a prescription veterinary diet intended for dogs with urinary problems, so it should only be used under veterinary supervision and may not be necessary for healthy dogs without urinary issues.
  • Relatively low as-fed protein (typical for many urinary therapeutic wet diets) may not be ideal for dogs that need a higher-protein regimen unless specifically advised by a veterinarian.

Top 5 Ingredients Explained

01
Water
Water is an essential nutrient and the primary solvent and moisture component in pet foods, especially wet and canned diets, and is also used in processing and to adjust texture and palatability. It is vital for digestion, nutrient transport, temperature regulation and waste removal in dogs and cats; pets must have constant access to clean water as dehydration can quickly lead to serious health issues and requirements increase with activity, heat, or illness, while moisture in wet food can help meet part of their daily needs.
02
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.
03
Chicken Liver
Chicken liver is a nutrient-dense organ meat commonly used in pet foods and treats as a highly palatable protein source and flavor enhancer, providing concentrated vitamins (especially vitamin A and B-complex), iron, and copper that support energy metabolism, red blood cell formation, and skin/coat health in both dogs and cats. Because it is so rich, liver should be fed in moderation—excessive intake can cause vitamin A toxicity, and its high fat content and risk of bacterial contamination mean it should be properly sourced or cooked and limited for pets with pancreatitis or specific dietary restrictions.
04
Pork By-Product
Pork by-product is a common protein and flavoring ingredient in pet foods made from non-rendered portions of the pig such as organs, connective tissue and trimmings, supplying animal protein, fat, B vitamins, iron and other trace minerals that help support energy, muscle maintenance and overall nutrition for dogs and cats. Because composition and fat content can vary by source, owners should be aware of potential pork sensitivities, higher caloric density, and sourcing/quality differences; ensure the complete diet meets species-specific requirements (for example, cats need adequate taurine) and consult the manufacturer or your veterinarian if you have concerns.
05
Chicken By-Product
Chicken by-product is a common protein ingredient in pet foods made from edible parts of the bird not typically consumed by people—such as organs (liver, heart), necks and other tissues—and is used to add protein, flavor and nutrient density. It can provide concentrated protein, essential amino acids, B vitamins and minerals (and may contribute taurine when organ meats are included), but composition and quality vary by source, so pet parents concerned about sourcing, higher ash/fat content or chicken allergies should check the manufacturer’s labeling and quality standards.
