When allergies are more likely
Allergic dogs often affect multiple paws and may also scratch the ears, face, armpits or belly. Recurrent ear infections and seasonal flares can provide useful clues.
When a local problem is more likely
Sudden licking of one foot can suggest a thorn, cut, broken nail, interdigital problem or pain. Carefully inspect without digging into painful tissue.
Why licking can worsen the problem
Repeated moisture and self-trauma can damage the skin barrier and encourage secondary infection, creating an itch–lick cycle.
