Not Interested in Dinner? It Could Be Pain.
When a dog or cat suddenly—or gradually—loses interest in food, it’s easy to chalk it up to pickiness or getting older. But a change in appetite can sometimes be an early sign of pain or discomfort.
-Pain can reduce the desire to eat. Discomfort can affect the neurochemical pathways involved in stress, inflammation, and mood, which may suppress appetite.
-Eating may become physically uncomfortable. Dogs experiencing chronic pain may avoid positions that worsen their discomfort, such as lowering their head to a food bowl or climbing stairs to reach their feeding area.
-The source of pain may not be obvious. Dental problems, neck discomfort, or abdominal inflammation can make chewing, swallowing, or even approaching food uncomfortable—leading to reduced appetite.
A change in appetite is worth paying attention to. If your dog is eating less than usual, especially alongside other changes in behavior or mobility, it may be a sign that something more is going on.
