Our pets can develop allergies and skin conditions in the same way that humans can. Unfortunately, they cannot tell us what the issues are so sometimes it’s hard for pet parents to notice the symptoms straight away. Dogs suffer from a variety of different skin conditions and allergies that routinely need a vet’s attention. This guide will help to highlight some of the most common allergies and how to treat them.
Here are the 5 most common skin conditions found in dogs:
1. Flea allergy dermatitis (FAD)
Flea allergy dermatitis should be fairly self-explanatory. It’s the most common skin disease in pets, and is caused by an allergic or hypersensitivity reaction to the saliva from a flea bite. Contrary to popular belief, dogs don’t need a huge flea burden to develop a reaction, and in fact can develop FAD if they have only 1-2 fleas on their body.
Flea treatment for dogs
Fleas can cause problems for dogs at any time of the year. The best treatment is prevention, which can be done with management of the skin allergy and disease. Short-term treatments can include topical steroids, antibiotic creams or shampoos, and oral antihistamines, steroids and antibiotics. Use a gentle, sulphate-free shampoo designed just for dogs as well, as you don’t want to strip the skin’s oils, especially if you’re using a spot-on flea treatment.
2. Food allergy dermatitis
This condition, which can also include food intolerances, is much less common than FAD or Atopy. It usually develops in dogs from one year of age onwards. If you suspect your dog may be suffering a food allergy, it is recommended to change to a strict food elimination trial diet for three months. This usually involves feeding your dog a sole protein diet using food that your pet has never had before, e.g. kangaroo and pumpkin, and nothing else. If the symptoms improve over this time, there is a possibility your dog has a food allergy. At the end of this time, test your dog by going back to the regular diet and monitor if symptoms recur. If they do, chances are it is a food allergy. The best solution is to work closely with your vet to find out which food is the cause. The most common allergens in dogs in Australia are beef, chicken and wheat.

Once you know what proteins or foods your dog is allergic to, simply avoid them in the diet. Alternatively, feeding your dog a commercial diet with hydrolysed proteins can be an option in some cases.
Mange is a skin disease of dogs, which is commonly caused by two types of mites: Demodex or Scabies. Demodectic mange is the more common of the two. Demodex mites are normally found on all dogs and don’t usually cause any problems. However, when there is an abnormality in the dog’s immune system, either in the skin or body, Demodex mites can thrive, causing hair loss and skin damage. This is followed by secondary bacterial infections and itching. Dogs with Demodex often don’t itch in the beginning. Often the first symptoms you will see are spots of hair loss starting on the face. Scabies, whilst less common, is extremely itchy and is usually contracted from native wildlife, such as wombats, or other infected dogs. It is more common in rural areas or suburban fringes. Scabies, but not Demodex, can also be passed on to people so if you start itching, make sure you tell the vet.

Both causes of mange are treated by administering the appropriate parasiticide until symptoms disappear. These mites are treated very differently, so it is important to go to your vet for an accurate diagnosis. The vet will do a skin scraping procedure before starting treatment.

4. Hot spots
Hot spots are another common skin disease seen on dogs. Its medical name is traumatic pyodermatitis. It usually appears as a discrete moist patch of hair loss on your dog’s skin that is very itchy. Often, it can be purulent with a discharge of pus, which tends to smell bad. They can be caused by anything that irritates your dog’s skin including infections, wounds, flea bites, etc, leading to the dog chewing at the skin. It then gets worse through persistent chewing and licking, which in turns causes further infection and itching. These wounds usually end up with a secondary bacterial infection.

Treatment usually involves clipping and cleaning the affected area, followed by a dose of topical antibiotics. In severe cases, oral antibiotics or corticosteroids may be prescribed to help reduce the itching, offering quick relief to your dog.
There can be many reasons why your dog may have itchy or irritable skin. Hopefully you are now armed with the information you need to handle your dog’s scratching. If your dog’s symptoms persist, please consult your local vet clinic.
