Skin Rashes on Dogs – Causes and What are They?

What Causes Dog Skin Rash?

The likelihood of your pet suffering from a skin rash at least once in its lifetime is fairly high.  Generally, a dog rash is not a cause of major concern for most people, since it can go away on its own after some time.  However, these rashes can be very uncomfortable and painful, leading to a much larger health problem.  It is important to treat your dog if it has a rash, so that it may be a happy and healthy animal.  The causes of skin irritations and rashes are many, and vary depending on the animal’s environment.

Common rashes are caused by fleas, mites, ticks, yeast infections, food allergies and reactions to detergents and environmental pollutants.  A dog’s stomach area is usually the most sensitive and in most cases, the worst-affected.  If you find that your dog is constantly scratching its stomach or legs, it may be trying to soothe an itchy rash.  We recommend Renuplex medicated dog shampoo that can be found at We have tested it and it has worked very well.

Other Causes of Rashes in Pets

Environmental allergies are a leading cause of rashes in dogs.  These allergies can include exposure to chemicals in pesticides, herbicides, insecticides, household detergents, shampoos and other similar items.  Rashes caused by these chemicals are normally red, hot, itchy spots that appear raised.  The best ways to treat these rashes are to discontinue the dog’s contact with the chemicals, and apply milk of magnesia to the rashes.  Other natural cures include rubbing diluted baking soda or green tea on the affected area.

External and internal parasites can also cause dog rashes.  Rashes caused by fleas are usually red pimple-like bumps, and can be treated with flea medication purchased from a veterinarian’s office.  On the other hand, rashes caused by mites appear raw and can be treated with miticide.  Internal parasites such as worms can also cause belly rashes and to treat them, a veterinarian must first thoroughly examine the dog rash to identify the type of worm before prescribing a treatment.

Treatments for Rashes

Yeast infections sometimes cause skin rashes on dogs. Rashes caused by yeast infection have an unpleasant odor and appear red and flaky. They sometimes leave scaly patches on the skin. Your dog should be examined by a veterinarian who will prescribe oral medication to treat fungus. Sometimes, special shampoo may be recommended for treatment of the infection. For more information on yeast infections please reference Immune-mediated disease can sometimes manifest itself in the form of red pimples on the dog’s nose. If not treated early, the rash can easily spread to other areas, causing open sores to appear on the animal’s skin. The rash can only be treated by a qualified veterinarian. The vet will first diagnose the disease and perform a biopsy on the infected area. A corticosteroid is usually prescribed to treat the infection. Owners of dogs affected by this disease are usually advised to keep the dog out of sunlight until it is completely cured.

Seborrhea is another condition that can be very irritating. It is the canine form of dandruff. It makes the dog’s skin appear flaky, and sometimes red pimples can appear. To treat seborrhea, anti-dandruff shampoo specially made for dogs can be used. The dogs should be cleaned frequently. Shampoos containing benzyl peroxide and salicylic acid can be dangerous, it is always best to use a natural shampoo.

My Dog Has Developed Many Hot Spots on Her Belly

Review of Evolutionsupply Skinplex and Enzymes and RenuPlex Shampoo for dog hot spots

Hi all, I wanted to share some some information with you regarding my Golden Retriever. About a month back she started to develop a skin rash and was licking and scratching all of the time. Her coat was literally falling off, and the rest she seemed to be chewing. It actually got so bad that the dog hot spots began to bleed and blister. We eventually went to the veterinarian and he prescribed a cream as well as steroids. While the cream had some success the steroids made her bloat up and gave her just horrible digestive issues (yes diarrhea) and her mood become bad. We never experienced such a bad case of hot spots on dogs that we had for many years. Eventually we stopped the steroids and skin infection stayed the same. We continued the prescribed cream, but like I said not sure how much it really helped. By now these dog hot spots began to form dry and itchy skin around them making her whole body even worse. In fact another passed and the poor thing was in so much pain. We tried medicated dog shampoos, even used coal tar, but had little success. So back to the veterinarian we go and she gave us a new antibiotic cream just for, as she said severe cases of hot spots on dogs and Candida yeast infection. Well it turns out that this cream was also steroid based and while it did help more than the first one, it came with even worse side effects so eventually we stopped it as well. We finally stumbled upon evolution pet supply at and tried their products for dog hot spots and after about a week we saw a small improvement and by week 3 over 50% of the skin problems and sores were healed. By months end we were just about back to normal. Now here skin is wonderful and she does not scratch or itch herself anymore. They had a choice of products like a medicated shampoo, a moisturizing spray, salmon oil and enzymes. Remember that Shampoo alone with not cure dog hot spots, enzymes should also be used.

How we used the Skinplex enzymes and Renuplex dog shampoo on her dog hot spots?

We went with the dog shampoo, enzymes, and spray. Used the shampoo two times a week for 2 weeks and then once a week. Used the spray every day for first 2 weeks and then about once a week after that. Used the enzymes everyday (she loves them, u just sprinkle a little bit over their food in morning.) I just cant say enough about how well it worked. After speaking with them they indicated that the shampoo and spray will kill the bacteria and growth to let the skin heal and moisturize, but it is the enzymes that actually stop the hot spots and keep them away. For this reason we give her the skinplex enzymes everyday and her coat is doing just so great, we could not be happier! Just wanted to share this article with everyone and recommend – it is nice to see these specialized companies with products that actually work. for us it was the skinplex enzymes and the renuplex dog shampoo. Hope this helps with anyone else’s dogmedical treatment for hot spots on a little dog hot spot problems!
