A lick granuloma , also known as acral lick dermatitis , is a skin disorder found most commonly in dogs , but also in cats. In dogs, it results typically from the dog's urge to lick the lower portion of one of their legs. The lesion can initially be red, swollen, irritated, and bleeding, similar to a hot spot wet eczema. The animal's incessant licking of the lesion eventually results in a thickened, firm, oval plaque , which is the granuloma. A major cause of lick granuloma appears to be psychological, related to stress, anxiety, separation anxiety , boredom, or compulsiveness.
