Hartz Companion Animal - Shampoo Therapy in Dogs and Cats


Published on

With the availability of effective
topical flea products, shampoo therapy
had fallen by the wayside in veterinary
dermatology. However, recent evidence
has shown that percutaneous absorption
of allergens plays a significant role in
propagating, and possibly even
potentiating, allergies in our pets.
There are several guidelines to convey
to clients regarding the use of veterinary
shampoos. First, the use of cool water
and contact times of 5 to 15 minutes
allow for hydration of the skin and a
sufficient period for penetration and
action of the active shampoo ingredients.
Bathing frequency is also important and
depends on the presence of skin disease
as well as the shampoo to be used.
