There are many different reasons why your dog is constantly scratching. These can include allergies to the environment and food, infection, poor nutrition, and flea infestations. Fleas are one of the most common but also one of the most preventable causes.
Flea infestations will not go away by themselves and will progressively get worse. If left untreated, fleas can cause a dull coat, dog hair loss and flea allergy dermatitis which is a common allergy to flea saliva. In severe, untreated cases it can also cause anaemia and lethargy, therefore it is important that you regularly use a flea treatment on your dog to prevent this cause of skin irritation. However ensure you use a brand recommended by your vet as some cheap brands are not effective and have even caused skin problems in dogs.
