Why does my dog have spots on his skin

Just like in people, there are many causes of pigmentation in the skin, many of which are nothing to worry about, but some can reflect a more serious disease process.  Should you worry about black patches on your dog’s skin? Many dogs will have naturally pigmented skin under their hair in certain areas and so if this has always been the case then it is likely nothing to worry about.  New areas of pigmentations are best to be examined by a veterinarian and investigated if something of concern is found. 

A very common cause of dark pigmentation in the skin is referred to as lichenification, where the, black patches are caused by chronic irritation. These patches or  can appear anywhere on the body of a canine such as the back, tail, legs and so on.  Whilst the skin changes themselves pose no risk, it is best to investigate the underlying cause of the irritation, which has often resulted in itching and scratching and therefore a reduction in your dogs happiness quality of life..  Common triggers include infestations with fleas or other parasites, food or environmental allergies, bacterial or fungal infections or, very commonly, a combination of these factors. 

New and growing areas of pigmentation are best to be examined by a veterinarian and most of the time your mind can be put at ease quickly.  In some situations the skin changes, as part of the bigger clinical picture, may suggest another disease process such as an imbalance in your dogs naturally occurring hormones.  If this is the case,  further investigations and treatments can be discussed.  Lastly, just as in people, some skin colour changes can represent a more sinister process, and in these scenarios taking a sample of the skin in the form of a skin biopsy is the best approach.
