What is the “White Salt Line” on a Dog’s Nose?

What is the "White Salt Line" on a Dog's Nose

The white salt line on a dog’s nose occurs when a dog develops small white patches or linings on their nose. This white lining or patches are generally easily visible on dogs with dark-colored noses, mostly black.

This may happen due to various reasons depending upon different factors. One such factor is their age; as the dog gets older, they tend to develop some changes in their body, including pigmentation in their furs and noses.

Certain dogs observe these color changes or white color occurrences in their body, especially when they are getting too much sun exposure. Too much sunlight causes the nose to develop small spots.

Allergies are another factor that creates a white salt line on a dog’s nose. A dog’s nose is one of its biggest assets; if they have allergies to a certain object or substance and a dog smells it, the irritation starts, and the color of its nose changes, which may result in white patches or salt lining.

Another rare but possible reason why a dog’s nose pigmentation is affected is if they have a medical condition; medical conditions and medications do affect a dog’s pigmentation and their ability to smell.

6 Causes for the Appearance of the White Salt Line

There are certain causes why a white salt line is appearing on your dog’s nose and body. While some of those causes can be natural with minor implications, others can be very serious and need medical attention straight away.

Let’s have a look at some of the common causes of white salt lines on dog’s noses.

1. Vitiligo


A very rare skin disease known as Vitiligo is one of the primary causes of white patches and salt lines in dogs. This skin disease causes depigmentation and turns the color of your skin or nose white.

This rare skin condition starts from the face and or around the nose area and then slowly spreads toward other parts of the body, such as the neck, back, or other parts of the body. It is mostly hereditary and does not raise any major health concerns.

2. Nasal Hyperkeratosis

Yeah, everyone has a hard time reading the word, but as much trouble as reading this word causes, it is even more trouble for the dogs.

Nasal Hyperkeratosis is said when there is abnormal production of keratin in a dog’s skin, which makes up a nose. This keratin, when bulged, causes white patches on your dog’s nose.

In some cases, it can be small, but in the majority of cases, the white patches can grow up to an inch. It is also chronic, so as an owner, you have to treat this whole life.

Nasal Hyperkeratosis can show as white dry patches in the nose; although it is not considered harmful, it can be very irritating and sometimes uncomfortable for your dogs.

Snow Nose

The name suggests what it means. A dog’s snow nose is said when they get a white patch or a white salt line right as the weather changes.

It generally starts off with the middle of the nose and then can spread to the entire nose, turning it pinkish or whitish. Some experts say it is because, during the winters, there is less sun exposure to your dogs.

But snow noses can happen to dogs irrespective of whether they live in snowy conditions or warmer areas. The white or pink patch goes away in a week or a month, or in some cases, it may last a whole lot and can be permanent.

It does not harm your dog in any way, and it is considered a mere cosmetic change in your dog and won’t affect their ability to smell and sniff.

Pemphigus Foliaceous (PF)

One big and very common reason for a white salt line on your dog’s nose can be a kennel nose. If your dog spends too much time in their kennel crate, they may develop this condition.
