Dog Skin & Coat Supplement Soft Chews Chicken Flavor
Verified May 26, 2026
A daily soft-chew supplement for adult and senior dogs that focuses on skin and coat support rather than whole-body nutrition. It uses chicken as a key flavor component and provides omega-3 and omega-6 fatty acids from fish oil and flaxseed, along with added zinc. This can be a useful add-on for dogs who may benefit from extra fatty acids on top of their regular complete diet.
This is a well-formulated skin and coat supplement for adult dogs, with a clear focus on providing meaningful amounts of omega-3 and omega-6 fatty acids plus zinc. It’s designed to complement, not replace, a complete and balanced dog food and offers a palatable soft-chew format that most dogs accept easily. It may be a good option for dogs with mild skin or coat concerns who are already on an appropriate main diet.

At a Glance
KibbleLab Review
Strengths
- Provides defined amounts of key fatty acids (EPA, DHA, ALA, linoleic acid) that are important for skin and coat health, as well as added zinc.
- Uses fish oil and flaxseed as primary omega-3 sources, which are more effective than relying on plant oils alone for these nutrients.
- Soft-chew format with real chicken and natural flavors tends to be easy to give as a daily supplement for most dogs.
- Calorie content per chew (about 20 kcal) is clearly stated so owners can factor it into the dog’s total daily intake if needed.
Considerations
- This is a supplement, not a complete and balanced diet, so it must be fed alongside a regular dog food that meets all nutritional requirements.
- Contains chicken and wheat, which can be triggers for dogs with known allergies to these ingredients.
- Adds extra calories, which can be important to account for in small dogs or those prone to weight gain, especially at higher chew amounts for larger dogs.
- Dogs with very sensitive stomachs may need a gradual introduction to fatty-acid supplements to avoid loose stools.

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.
