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