Why Do Dogs Lick Their Paws?

Sometimes an underlying systemic health problem causes dry or itchy skin. Two common culprits are Cushing's disease, which involves the production of too much cortisol, and hypothyroidism, which means the thyroid gland is underactive. Both can result in dry, itchy skin and odd hair growth. Fortunately, both conditions are usually easy to treat, but you will need to visit your vet to get a proper diagnosis and start your dog on the appropriate medications.
