When Scratching Turns Into Self-Injury
Dogs do not always know when to stop scratching.
Severe itching can cause nonstop licking, chewing, and biting until the skin, paws, or toes become badly injured. In this case, repeated self-trauma caused irreversible damage to one digit, which eventually had to be amputated.
Persistent scratching is not just a bad habit. It may be caused by allergies, parasites, skin infection, pain, or another medical condition that needs treatment.
Watch out for:
• Constant licking or chewing
• Bleeding, swelling, or open wounds
• Hair loss or darkened skin
• Scratching that interrupts sleep or normal activity
Do not wait for the injury to become severe. Early veterinary care can help control the itching, identify the cause, and prevent self-mutilation.
