My dog has been scratching a lot. What could be causing this?

It is possible that your dog may have an allergy or irritation from something in the environment, such as pollen, dust, mold, or pet dander. You can try using over-the-counter antihistamines and calming shampoos to help reduce itching. Additionally, you should check for any flea or tick infestations that may be contributing to your pup's scratching behavior.
