What’s wrong with a dog’s nose fading? What factors can cause a dog’s nose to fade?
Vitiligo
Vitiligo can also cause the nose to discolor. Vitiligo is an immune system disease in dogs. Dogs with this disease will have patches of white spots on their skin.
Allergy
Some dogs often come into contact with plastic rice bowls and are sensitive to plastic products, which can cause contact skin inflammation, discoloration of the nose, and even swollen lips. The solution is just to replace the plastic rice bowl with stainless steel.
Injuries
Dogs’ noses can also turn pink if they have abrasions or scratches, or if they have experienced other illnesses or trauma. Color will return as the injury heals.
