why do dogs bite their tails

Dogs bite their tails for a variety of reasons, typically related to skin irritation, health issues, or behavioral causes. Common physical causes include fleas or ticks causing itching, intestinal parasites irritating the area, skin infections, allergies, anal gland problems, or injuries such as fractures to the tail. Behaviorally, dogs may bite their tails due to anxiety, stress, boredom, or compulsive disorders. Sometimes, tail biting can be a sign of underlying physical discomfort or a coping mechanism for emotional distress. If tail biting becomes frequent or severe, it is important to consult a veterinarian to diagnose and treat the cause appropriately.
