Irritated skin can really make your dog miserable. It's no picnic for you either, as you listen to your buddy scratch, lick, and chew himself all night. Unfortunately, there are many health issues that can cause your dog's skin to be itchy, and sometimes pinning down the problem can be a lot of work. Here are some of the potential causes of your dog's red, itchy, irritated or flaky skin.
External Parasites in Dogs
- Fleas: Flea allergy dermatitis is an allergic reaction to flea saliva (caused by flea bites).
- Mange: Sarcoptic and demodectic mange are both caused by different skin mites. Proper diagnosis and identification by your veterinarian is critical for correct treatment.
- Ringworm: Despite its name, this is not an actual worm. It's actually a contagious fungal infection that can affect pets and humans. Ringworm causes round patches of itchy skin and hair loss.
- Yeast Infection: Malassezia Dermatitis is a fungal infection caused by an overgrowth of the body's normal yeast. Yeast infections may be secondary to allergies.
- Bacterial Infection: Pyoderma is a bacterial infection typically caused by the Staphylococcus bacteria. Bacterial infections are often secondary to allergies and sometimes cause hot spots in dogs.
Canine Atopic Dermatitis
Canine atopic dermatitis is caused by environmental allergies, like pollen and dust mites.. can give your dog itchy skin and goopy eyes. There are medications available to help ease the irritations that go along with allergies.
For severe skin problems, your vet may recommend allergy testing.
Food Allergies in Dogs
It is quite common for dogs to have food allergies. Most dogs with food allergies are actually allergic to the protein source in the food, such as chicken or beef. Some dogs are allergic to carbohydrate ingredients like corn, wheat, or soy.
Dogs with food allergies do best on limited ingredient diets that consist of one main novel protein (something the dog has not been exposed to much, like duck or fish) and one main carbohydrate, such as sweet potato. You may consider feeding a grain free diet or natural diet to see if that helps.
Treating Your Dog's Skin Problems
Many treatments are available to help soothe your dog's skin and address the primary cause. Your veterinarian will be able to help you start a treatment program that will hopefully have your dog comfortable again in no time. However, it's important to understand that skin problems in dogs are often ongoing issues that cannot be cured. These skin issues must be managed by you and your vet over time. It's important to be proactive about skin issues in your dog so they do not get out of control. If so, you can help keep your dog as comfortable as possible.
