What are some common signs that a dog might be feeling anxious?

Common signs of anxiety in dogs include excessive barking, pacing, hiding, trembling, and destructive behavior such as chewing furniture or scratching doors. Dogs may also exhibit a reduced appetite, excessive drooling, or increased clinginess to their owners. Some dogs may urinate or defecate inappropriately due to stress. Behavioral changes like these can indicate anxiety, which can be triggered by factors such as separation, changes in routine, or unfamiliar environments. Consulting a veterinarian or a pet behaviorist can help identify the cause and determine appropriate interventions.
