Golden Retriever (Detailed Introduction)

       Usually, most dogs have black noses, but nose color varies by breed. Regardless of breed, a dog's nose color is generally solid. So what to do when a dog’s nose loses color? First, we need to find out the cause of the discoloration. Generally, dog nose discoloration is divided into normal and pathological types. Only by understanding the cause can the problem be solved.

       1. Snow Nose: People call the winter discoloration phenomenon "snow nose" because the enzyme responsible for pigment deposition in the dog's nose, "tyrosinase," is very sensitive to temperature. It works stronger in warm environments, so a dog’s nose tends to lose color in winter.

       2. Allergy to Plastic Products: Contact dermatitis caused by plastic feeding bowls can also cause a dog’s nose to lose color, and usually the dog's lips will swell as well. Switching to a stainless steel feeding bowl can prevent these symptoms.

       3. Vitiligo: Vitiligo is an autoimmune disease in dogs, and the dog's fur will also have patches of white spots.

       4. Nose Scratches or Abrasions: Usually, the nose color will recover after injuries or illness heal.

       5. Nutritional Deficiency: Vitamin B complex helps pigment deposition, and if a dog lacks it, pigment deposits poorly, causing the nose color to lighten naturally.

       It can be seen that normal aging causes nose discoloration, but insufficient nutrition and some injuries can also cause this problem. Therefore, if it is not due to normal aging, consider whether your dog lacks nutrients or has an illness. Seek veterinary examination and treatment as soon as possible.
