10 Warning Signs Your Dog Needs Immediate Veterinary Attention
8. Changes in Behavior or Mood

Behavioral changes in dogs can be subtle yet significant indicators of health issues. A normally friendly dog that becomes aggressive or a playful dog that turns withdrawn might be experiencing pain, anxiety, or neurological problems. Other behavioral changes, such as increased vocalization or restlessness, can also signal discomfort or distress. Paying attention to your dog's behavior and mood can provide valuable insights into its well-being. If you notice any drastic changes, consulting a veterinarian or a professional behaviorist can help identify the cause and guide you in providing the necessary care.
