Canine Selected Protein PD Wet Loaf
Verified Jun 11, 2026
This is a veterinary therapeutic wet food formulated for adult dogs who need a selected protein diet, often due to suspected or confirmed food sensitivities. It uses duck as the primary animal protein along with potato and hydrolyzed soy as carbohydrate and protein sources, and includes added EPA/DHA and antioxidants to support skin and overall health. The loaf texture can be helpful for dogs that prefer a soft, moist food or have difficulty with kibble.
This is a thoughtfully designed veterinary diet for adult dogs with food sensitivities who need a selected and relatively novel protein source. Duck and potato are well-established options in elimination and sensitivity diets, and the inclusion of hydrolyzed soy helps provide a complete amino acid profile while lowering the chance of triggering an immune response. It’s a good option when your veterinarian recommends a prescription diet to help investigate or manage suspected food allergies, especially with concurrent skin concerns.

KibbleLab Review
Strengths
- Duck as a named primary animal protein plus potato and hydrolyzed soy provide varied, highly usable protein sources suitable for many dogs with food sensitivities.
- Formulated as a complete and balanced maintenance diet according to AAFCO profiles, so it can be used as a sole adult diet under veterinary guidance.
- Includes fish oil (source of EPA and DHA) and an antioxidant blend, which are commonly used to support skin, coat, and overall immune health in sensitive dogs.
- Wet loaf format is energy-dense (429 kcal per can) and can be easier to eat for dogs with dental issues or poor appetite.
Considerations
- This is a prescription therapeutic diet, so it should only be used under the direction of a veterinarian, particularly if it’s part of a food trial or allergy workup.
- Despite being a selected protein diet, it still contains common allergen sources (duck and soy), so it may not be appropriate for dogs that react to these ingredients.
- The as-fed protein percentage appears low at first glance, which is normal for high-moisture canned foods but may be a consideration for very high-protein diet preferences.

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
Duck
Duck is used in pet food primarily as a flavorful animal protein and fat source, commonly included in limited-ingredient or novel-protein formulas for dogs and cats. It supplies high-quality amino acids and energy and can help pets with sensitivities to common proteins, but it is relatively rich in fat (so may be unsuitable for low‑fat or pancreatitis-prone animals), can still trigger allergies in some pets, and requires proper cooking/processing and handling to avoid bacterial contamination.
03
Potato
Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.
04
Duck Liver
Duck liver is an organ meat used in pet foods and treats as a concentrated protein and highly palatable micronutrient source, supplying bioavailable vitamins (notably vitamin A and B12), iron, and copper for both dogs and cats. It is nutrient-dense and beneficial in moderation but should be included as part of a balanced formula because excessive liver can lead to hypervitaminosis A and mineral imbalances, and it should be properly processed to minimize pathogen risk.
05
Potato
Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.
