Perhaps the most common of cat and dog skin conditions is flea allergy.  It is easy to treat – provided all aspects of the flea problem are tackled vigorously - see our Flea Treatment Section for easy to administer solutions. The next most common type of skin condition is allergic skin disease where the pet develops an allergy to things like house dust mites or grass pollens. This is a very hard condition to deal with and an absolute cure may be impossible, however, with the right combination of treatments long-term relief is achievable.
