• Dogs are complex animals that have specific nutritional requirements, some of which they cannot attain through their typical diets. Supplements, either in pill, liquid, or gel form, help dogs obtain their proper vitamins. Some vitamins are particularly helpful in maintaining a dog's skin and coat.
  
  

Vitamin A

• Vitamin A is important to a dog's skin and coat, and is vital in puppies and often packed into their mother's milk. It promotes the growth of the dog's coat, making it thicker and fuller. Thinning hair or bald patches on your dog can be signs of a vitamin A deficiency.
  
  

Vitamin B Complex

• Vitamin B complex is one of the many forms of vitamin B, which is found in most dog supplements. It promotes a healthy coat and also helps with the health of the skin. At the same time, vitamin B complex helps the dog's visual acuity, strengthens the mouth and keeps the liver healthy.
  
  

Vitamin C

• A versatile supplement, vitamin C not only helps the immune system, but promotes cellular growth. This leads to faster healing and strengthens the dog's skin.
  
  

Omega-3s

• Omega-3s are special varieties of unsaturated fatty acids typically found in fish oil or fish oil tablets and help promote a thick, lustrous coat when added to canine vitamin supplements.
