Summary
Acral lick dermatitis (lick granuloma) was diagnosed in 11 dogs on the basis of history, physical examination, and histopathologic findings. A predilection for the left forelimb was noticed.
All 11 dogs were given the narcotic antagonist naltrexone. Successful treatment (cessation of licking, reepithelialization of lesions) was seen in 7 dogs. All 7 dogs' lesions recurred when naltrexone was stopped, but reepithelialized in 5 dogs when the drug was readministered. Adverse effects (drowsiness, withdrawal from owner) were seen in 1 dog, but resolved within 48 hours of stopping the drug.
