Here's what you should do:
* Return to your veterinarian: It's important to rule out any underlying medical reasons for the change. The vet can conduct a thorough examination, possibly including bloodwork and skin scrapings, to determine the cause.
* Detailed information: When you visit the vet, provide them with as much detail as possible about the scratching change:
* When did it start?
* Was the scratching excessive before?
* Were there any other changes in her behavior? (e.g., lethargy, appetite changes)
* Consider other possibilities: There could be factors beyond medical issues, such as:
* Environmental changes: New cleaners, detergents, or even a change in season can affect skin sensitivity.
* Stress or anxiety: A stressful event (like a move or new pet) can manifest in unusual ways.
* Diet: A change in diet might be causing an allergic reaction.
Important: It's crucial to trust your veterinarian's diagnosis and treatment plan. They're the best equipped to understand your dog's specific needs and recommend the right course of action.
