This is a rare and harmless skin condition that affects English springer spaniels under 2 to 3 years of age. Dogs with psoriasiform-lichenoid dermatosis develop wart-like bumps on their inner ear and/or abdomen.
What to Look for
This condition will not affect the health of your dog, only his or her appearance. Dogs with this condition develop reddened or yellowish wart-like bumps on their inner ear flaps and groin, and eventually on their face and abdomen.
A skin biopsy is necessary to make the diagnosis. This is a simple procedure, done with local anesthetic, in which your veterinarian removes a small sample of your dog's skin for examination by a veterinary pathologist. The biopsy will show changes characteristic of this condition.
There has been little success with treatment. The condition tends to wax and wane.
