Skin & Coat Dog Supplement Soft Chews Chicken Flavor
Verified May 26, 2026
A daily soft-chew supplement for adult and senior dogs, this product focuses on supporting skin and coat with added omega-3 and omega-6 fatty acids from fish oil and flaxseed, plus zinc. It uses chicken as a key animal ingredient and has a moderate fat content for a supplement chew. This is designed to be given alongside a complete dog food, not as a primary diet.
Nutritionally, this is a well-thought-out skin and coat supplement with defined amounts of key fatty acids (EPA, DHA, ALA, linoleic acid) and zinc, which are all important nutrients for skin and coat health. The ingredient list is straightforward for a chew format and avoids artificial colors and flavors while using established preservatives. It should suit most healthy adult and senior dogs whose owners are looking to add targeted fatty acids on top of a balanced diet, as long as chicken and wheat are not an issue for that dog.

At a Glance
KibbleLab Review
Strengths
- Provides clearly specified amounts of omega-3 fatty acids (EPA, DHA, ALA) and omega-6 (linoleic acid), which are important nutrients for skin and coat health.
- Includes zinc in a chelated form (zinc methionine complex), which can be well-absorbed and supports skin integrity.
- Soft chew format with real chicken is generally palatable and easy to give once daily, which helps with consistency.
- No artificial colors or flavors, and uses safe preservatives like citric acid and mixed tocopherols.
Considerations
- Contains chicken and wheat flour, which can be problem ingredients for dogs with known chicken or wheat allergies or sensitivities.
- This is a supplement, not a complete and balanced diet, so it must be fed alongside a full dog food that meets all nutritional needs.
- Each chew adds extra calories (about 20 kcal per chew), so portions of the main diet may need minor adjustment in smaller or less active dogs to avoid weight gain.

Top 5 Ingredients Explained
01
Millet Flour
Millet flour is a gluten‑free cereal ingredient used in pet foods primarily as a carbohydrate source and binder, contributing energy, texture in dry kibbles, modest plant protein, and dietary fiber. It provides B‑vitamins, manganese, and fiber that can support canine digestion, but because cats are obligate carnivores their carbohydrate intake should be limited; millet is generally well tolerated when cooked/processed for digestibility, though like other grains it contains phytic acid that can reduce mineral availability if not properly handled and should be balanced within a complete diet.
02
Glycerol
Glycerol (glycerin) is used in pet foods primarily as a humectant and sweetening agent to retain moisture, improve texture and palatability, and serve as a solvent or carrier in wet foods, treats, and liquid supplements. It provides a modest source of metabolizable energy for dogs and cats, but in large amounts can cause gastrointestinal upset and may affect blood glucose, so products intended for diabetic pets or sensitive animals should be used with caution.
03
Wheat Flour
Wheat flour is commonly used in pet foods as a carbohydrate source, binder and extender that provides digestible energy, some protein (including gluten), and small amounts of fiber and B‑vitamins when enriched. While generally safe and economical for many dogs, it is not a required ingredient for obligate carnivores like cats, can contribute to excess calories or a high glycemic load, and can trigger food allergies or gluten sensitivity in susceptible pets, so animals with known wheat sensitivities or weight concerns may benefit from wheat‑free formulations.
04
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.
05
Flaxseed
Flaxseed is used in pet foods as a plant-based source of alpha‑linolenic acid (ALA) omega‑3, soluble and insoluble fiber, and modest protein, often added to support skin and coat condition, digestive health, and kibble texture; ground seed or flaxseed oil is more digestible than whole seed. Dogs can partially convert ALA to long‑chain EPA/DHA but cats convert ALA poorly and therefore still need marine sources for essential DHA/EPA; flax is calorie‑dense, prone to oxidation if not stabilized, and contains lignans (phytoestrogens) and trace cyanogenic compounds, so it should be processed and used in moderation.
