Skin & Coat: The Mirror of a Dog's Health!

Understanding Dog's Skin Layers:

The skin and coat forms the largest organ in dogs, comprising around 10-15% of the total body weight. The skin is composed of three layers- Epidermis, Dermis and Hypodermis.

• Epidermis: The epidermis is the outermost layer of the skin, made up of stratified squamous epithelial cells. It serves as a protective barrier against environmental damage, pathogens, and water loss. The epidermis does not contain blood vessels.
  
• Dermis: The dermis is the thick middle layer of the skin, located beneath the epidermis. It is composed of connective tissue and contains blood vessels, nerves, hair follicles, sweat glands, and sebaceous (oil) glands. It provides strength, elasticity, and sensation to the skin.
• Hypodermis: The hypodermis is the deepest layer of the skin, composed mainly of fat (adipose tissue) and connective tissue. It helps insulate the body, store energy, and cushion internal organs by absorbing shocks. It also connects the skin to underlying muscles and bones.
  

                               

Primary function of Skin & Coat in dogs:

Your pet’s skin and coat play vital roles in their health. Together, they function as an important part of the immune system, and are critical to maintaining proper hydration. 

The primary functions of skin and coat are:-

1. Immunity: The dermis houses immune cells like Langerhans cells, mast cells, and macrophages, which:
   
   1. Detect harmful invaders and trigger an immune response.
   2. Help in wound healing and tissue repair.
2. Protection: Acts as a barrier against external threats such as bacteria, viruses, parasites, and environmental hazards.
   
3. Thermoregulation: 
   
   1. In winters: Thick fur traps heat
   2. In summers: Shedding helps keep dogs cool
4. Hydration: Prevents excessive water loss and dehydration.
   

Coat structure of dogs is highly variable, depending on the breed and the geographical location they are located at. Breeds originating from cold regions have denser coats, whereas those originating from warmer regions have shorter coats

A soft and shiny coat is a signal of vitality and acts as an easy visual indicator of a dog’s good health.

Parameters for identifying "Good Skin Health" of your dog:

Here are the things a pet parent should look out for to determine the health of their dog’s skin and coat:-

• Minimal Non Seasonal Shedding: A dog’s coat seasonally sheds twice a year during Spring and Autumn. Consistent shedding throughout the year is not expected. It is a worrying sign. 
• Non-Smelly Coat: Although dogs have a characteristic smell in their body, smelly coats just a few days after bathing indicates skin issues.
  
• Softness & Glossiness: It is the most important indicator of good skin health. The coat should feel soft and shiny in general.
  
• Minimal Incidence Of Skin Infections: If a dog is recurrently having bacterial or fungal skin infections  it often involves an underlying nutritional deficiency.
  

Quick Tips for achieving healthy skin & coat:

Few easily implementable suggestions that you should consider by to ensure that your dog has a healthy coat:-

1. Nutrition: Diet plays a major role in maintaining skin health, and most skin issues often stems from nutritional deficiencies.
   1. Feeding a diet enriched in quality protein and essential fatty acids (Omega 3 and Omega 6) is recommended.
   2.  Micronutrients like Vitamin A, D, E, Zinc and Biotin also have a pivotal role in skin cell regeneration and hydration
      
2. Hygiene Protocols: Regular brushing (specially for long coated breeds) and periodic bathing with a dog specific shampoo keeps the skin clean and free of knots. Too frequent bathing should be avoided since it will strip off natural oils from the skin.
   
   1. Summers: Ideal bathing frequency for Long Coated Breeds is 2 weeks and for Short Coated Breeds is 3 weeks.
   2. Winters: Ideal bathing frequency for Long Coated Breeds is 5 weeks and for Short Coated Breeds is 6 weeks.
