A skin allergy may be giving your dog a unnecessarily uncomfortable life. A hypersensitivity to a substance that is usually considered harmless is the basic definition of allergy. Dogs get allergies in very much the same way people do. On a dog the biggest symptom of allergies generally appear on their skin. Luckily there are many products that can be found cheaply online that will help cure this allergy.

Common problems with contact allergies and atopy allergies may be the result of your dogs skin allergy symptoms. Physically touching a allergen with the skin is the cause of a contact allergy. Bedding, chemicals, plants, or cleaning products are the usual cause of an allergy of this nature. A atopy allergy would from a dog inhaling the allergen. This can be caused by fleas, chemicals or other airborne substances.

Fleas can also cause a dog to have symptoms of an allergic reaction appear on its skin. A flea is a small creature, not unlike a mosquito, that bits into the skin of an animal and sucks blood out. Fleas leave trace amounts of saliva. The saliva can carry proteins that act as allergens. These 3 things can cause symptoms such as itching, biting, face rubbing, redness of the skin, and small pimple like lesions.

In a worse case scenario, which is highly unlikely, for a dog suffering from allergies is a bacterial infection, which is also called a bacterial allergy. Common symptoms of a bacterial dog allergy include irritated red blotches on the skin, pus pockets, ringworm like skin formations. Hair loss that can be quite severe is also a common symptom of this kind of infection. Unfortunately a problem like this is usually secondary to other problems. A parasitism is a likely cause of the original infection. Parasitism occurs when a parasitic entity enters an mammal's body and bits down and attaches to an internal organ. The parasite will then feed on nutrients at the expense of the host. Aside from the obvious problems associated with parasitism it can also cause various other diseases. The only other thing that could cause this extreme scenario is a hormonal disorder. You would need a blood test for your dog to be sure about a diagnosis of a bacterial infection.
