Dog Skin Disease Picture Comparison is as follows:

1. Eczema

Manifests itself as a red, swollen area of skin that may feel warm when you touch it. Eczema can appear anywhere, but it often develops on the chest, buttocks or head, and can be caused by allergies, insect bites, infections and dogs licking that area too often.

Eczema is best treated even if you go to the vet in order to make sure your dog is getting the best treatment possible; it's one thing to be able to treat eczema, but if you don't find out what's causing the symptoms, the skin condition will keep recurring.

2. Mange

Mange and helminthic mites, they are both caused by mites, which are tiny extracorporeal parasites that can cause symptoms of infection when they colonize the top of a dog's skin or fur. This disease is easily spread from dog to dog. Infected dogs will scratch incessantly, causing bald spots, inflammation, mange scars and scabs. Mange usually starts on the face, ears or legs, but may spread throughout the body.

3. Bacterial dermatitis

One of the most common of the curable skin conditions is recurrent bacterial dermatitis, in which the dog develops round bald patches, flakes and scabs, and tiny inflamed rashes that evolve into more hardened patches. Bacterial dermatitis rarely occurs in the average healthy dog, so it's important to consider what potential triggers for dermatitis are present.

4. Moss

Moss is actually a fungus, not a parasite or anything like that, although it does have similar symptoms to mite onset: rounded patches of bald, scaly, flaky, red, swollen skin patches. Moss can be transmitted through close dog-to-dog contact, and is more common in puppies. It can also be treated with medicated baths, ointments or internal medications.

5, allergic skin disease

Basically, it is due to the diet is too salty, too fresh caused, but also may be due to paint, dust allergies.
