Acral lick dermatitis (ALD), commonly known as a "licking granuloma," is caused by persistent licking of a lower limb, which creates a firm, thickened, and often ulcerated plaque.
Most time owners notice that the dog is overly licking or nibble at the affected areas, especially on the top of the carpus joint.
While originally thought to be purely behavioural, it is more likely to recognise as a multifactorial problem often triggered by underlying pain, allergies, or infections.
Treatment is often long-term and will need to figure out if there is any underlying condition.
The licking behaviour can become an addictive, self-perpetuating cycle due to the release of feel-good endorphins.
Entertainment, such as toys, is good to help keeping attention away for the limb.
Over licking can cause further infection on the wound as well, early intervention is important to avoid getting worse.
Your vets will have a good examine, palpation and possible squeezing around the wound to check if any foreign bodies noticed.
Cytology might be required if infection is concerned.
Treatment can be combination of therapeutic approaches.
Physical barrier is the key to prevent further licking, such as Elizabethan collar or bandage. Medication might be necessary if infection, pruritus or painful condition detected.
Behaviour management is recommended to keep attention away, such as increasing exercise, social interaction, and mental stimulation.
