The appearance of spots is influenced by the development of bacteria and fungi that sometimes appear in hair that is often wet.
Owners of white and light brown dogs are usually very bothered by yellowish spots that form on the hair under the eyes or on the moustache and chin, and sometimes on the paws and around the genitals. Most of them think that the cause is excessive tearing which causes the hair to oxidize.
But it is not so. The causes of these stains are much more complex. As with many things, genetics play an important role. There are dogs whose hair will not turn yellow and those whose hair is yellow despite all the efforts of their owners. The appearance of spots is influenced by the development of bacteria and fungi that sometimes appear in hair that is often wet. The hair under the eye is wet in most dogs, but in those who are not white, no spots are visible.
This does not mean that your white puppy has clogged tear ducts and needs to be rinsed. In addition to the above, the appearance of jaundice is influenced by diet, possible allergies and, of course, the degree of effort invested in regular hygiene of these parts of the body.
It is very important to keep these critical areas dry, because both fungi and bacteria benefit from a humid environment. When a dog eats, you must protect your moustache and beard from coming into contact with food, and it is preferable that they do not come into contact with water either because of the various minerals contained in it.
Among breeders, there are also those who use antibiotics (locally, but more often systemically), especially before exhibitions, to whiten that hair. I do not recommend this because I believe that giving medicines for aesthetic purposes is not morally correct. If you are buying products to remove these stains, see if they contain an antibiotic. If yes, consult a veterinarian before use.
Bleach is also used to remove stains (the same as for strands in our country, mostly based on a high percentage of hydrogen), but great care should be taken so that the chemical does not enter the dog’s eye.
To remove these stains, daily care and occasional professional groomer treatments are needed. I would recommend anyone to consult their groomer in this regard.
White hair is extremely demanding and sensitive. Dogs that walk outside will always have slightly darker hair on their legs than those that live exclusively in an apartment.
Like I said, a dog can genetically have fantastic white hair that is not susceptible to ugly yellow spots, but such are rare. Most snow-white dogs, which we see in exhibitions, have daily special care, curlers for food and drink and certainly do not roll in puddles. And every breeder has their own little secrets.
The most important thing is that there is no pathological process in the background of the colour change. If you notice changes in your friend’s skin, be sure to seek the help of a veterinarian.
