Roundworms should not cause itching. They are transmitted through a fecal-oral route. Dogs often get it from ingesting infected soil. Some pet stores may carry de-worming medication but I would recommend getting appropriate treatment from your veterinarian.
There are many causes of itching in dogs. Common causes include allergies and dermal parasites--like mites and ringworm. Talk to your veterinarian about having skin tests done to check for mites and ringworm. Allergies are about control not cure. You and your veterinarian will work together to come up with a multi-modal treatment plan.
