Mange is a skin condition in dogs that is caused by an infestation of microscopic mites. Mites are transferable from one dog to another, but in healthy dogs mites simply add to the existing population on your dog and both mites and dog live harmoniously. This is because a certain number of mites on your dog is normal, but when mites multiply in one small area it can cause mild to severe skin problems. Seeking treatment for dogs with mange is important, which is why it is vital to know the symptoms of mange.
Instructions
Watch for excessive scratching. Dogs with sarcoptic mange often scratch themselves maniacally and obsessively. Typically the ears, elbows, face and legs will be affected, but other areas of your dog's body are also vulnerable to mange.
Watch for excessive biting and licking. Your dog will lick and bite the area he has mites for the same reason he scratches--it is irritated. Licking and biting at it repeatedly is soothing for your dog.
Check for hair loss. If your dog has mange, the constant scratching, biting and licking usually leads to bald patches, red patches, sores and scabbing. The areas your dog scratches can also become infected. The bald areas may look scaly or polka dot-like in appearance.
