What Causes the Black Patches on Dog Skin?
Dogs with acute skin allergies may develop black patches.. and the skin around the spot is thick and itchy! This is commonly referred to lichenification, and it is caused by irritation. If black patches appear without any sign of inflammation or change in the underlying skin, the condition is nothing worrying. The patch on the skin is either just a natural pigment variation or a response to chronic irritation from scratching and itching. Hydrogen peroxide and borax are among the most popular treatments for treating black patches on dogs. The best thing to do is to get your dog on a raw meat and bone diet immediately, which includes probiotics, coconut oil, digestive enzymes, or yogurt daily.
If these black skin patches look dry or disturbing to your dog, you should allow your vet to take a look. When vets first look at it, they might suspect it as flea infection. You may not see any fleas on your dog skin. If the dog is allergic to flea’s saliva (a very common allergy), one flea is enough to drive him crazy. If the flea product you used was not bought at your veterinarian’s office, then it probably was not an effective one. Flea contamination can be very complicated, consult your veterinarian for proper evaluation. This disease can be a major problem; it is usually treated with long-term antibiotics, generally for around 6-8 weeks.
In some cases, there can be a yeast infection too. This can be determined by your veterinarian with something called impression smear, where a glass slide is touched to the skin and after that, the stained is looked under the microscope. If yeast is present, they are treated with medicated shampoo twice a week for several weeks then once a week for several weeks afterwards.
Other common causes of severe itching are scabies. This is caused by microscopic mites that burrow into the pooch’s skin. The infection can be diagnosed by a skin-scraping in the vet office. Mosr of the time, the mange mite is not obvious with the scratching. Thus, even if the vet thinks it may be scabies, they normally go ahead and treat for it. Treatment is a topical solution known as Revolution that is applied to the back of the dog’s neck once, then again in 3-4 weeks.
Finally, chronic itching can be caused by food allergies or atopic state (regular dog allergies). Many dogs that react to steroids have a real problem of atopic, and not really a food allergy problem. Food allergies typically involve scratching at the ears and backside, instead of the continuous licking of the paws. Unfortunately, most pooches require antihistamines and steroids to stay comfortable. For some dogs, this period is just in the warmer months, however, for some, it is a problem throughout the year. A new drug known as Atopica is newly designed for veterinarian use. It can be very effective, without any negative side effects of using long-term steroids. Although it is very expensive, you can talk to your vet about ordering it for you if you are interested.
