Is it a skin disease?

Possible causes of red bumps on the body of a pooch are: insect bites, allergies, and skin diseases such as ringworm or eczema in dogs. If the red bumps are caused by allergies or skin diseases, it is recommended to take your dog to the vet for an examination and treatment. If the red bumps are caused by mosquito bites, disinfect the affected area with iodophor alcohol and then apply a special cream for dogs to treat mosquito bites.
