Shampoo Therapy of Various Skin Conditions

In this section, I will summarize the most common treatment modalities, their formulations (which may vary in different parts of the world), indications, and doses. Given that detailed discussion of individual drugs, their mechanisms of action, pharmacokinetics, and protocols is beyond the scope of this text, further reading may be required. See Recommended Readings.

Drugs marked with an * and a colored screen are potentially dangerous and the clinician inexperienced with these medications may consider offering referral to a veterinary specialist or seeking further advice from a colleague with more knowledge about that particular agent.

Shampoo Therapy of Various Skin Conditions

Shampoo therapy can provide effective management of dermatoses with both medical and cosmetic presenting complaints (Table 3-1). There are few adverse effects associated with shampoo therapy, although they are recognized. However, shampoo therapy is symptomatic treatment; it rarely "cures" a dermatosis.

Prescribing a shampoo involves selecting the proper shampoo for both the dermatosis and the client. Shampoo manufacturers have undertaken considerable research and development in order to produce formulations, which lather well, have an appealing smell, offer little irritation, and serve their intended purposes.

In addition to selecting the appropriate shampoo, the veterinarian's instructions will have a significant impact on the efficacy. The frequency of bathing and duration of skin contact time will influence the obtained result. A 10-minute contact time is generally recommended. This is a long time for the owner of a fidgety, shivering dog to wait and it will frequently be cut short! Techniques to improve contact time include:

> Take a clock into the bathing area and time 10 minutes accurately.
>Use the time for patting and bonding.
>Massage the skin for the full 10 minutes; it will usually be enjoyable for the dog and occupy both pet and owner.
>Take the dog outside to play ball or go for a walk with the soap still on (if climate permits).
>Rinse the shampoo off thoroughly for at least 5 to 10 minutes.

The frequency of shampooing will vary with severity and type of the disease process. In general, the more severe the disease, the more frequently bathing is indicated.

The major reasons for failure of shampoo therapy are:

1. Lack of client compliance (frequency and/or duration of application)
2. Incorrect selection of shampoo for the disease process
3. Shampoo irritation
