Arm Your Dog Against The Effects Of Aging
Skin and Coat
These conditions keep small-animal practitioners in business and are more common with age. As your dog grows older, expect to find increased sensitivity to allergens and less resistance to infection. Some skin and coat conditions are secondary to autoimmune problems or associated with low thyroid function and allergies. Tests now are available both in vivo and in vitro to help sort out allergies. Common problems are "hot" spots, loss of hair, dry scaly skin and chronic skin infections. There is an extensive range of over-the-counter and veterinary shampoos, rinses, dips, salves, etc., from which to choose. Some work on a given dog, some work on some dogs, some work on most dogs and many don't work at all, but the "hype" sounds good.
Virbac's Allerderm® and Allergroom® shampoos with their patented "spherulite" technology seem to be holding up well in the marketplace; i.e., the dog owners' experience mirrors the manufacturer's claims.39 Spherulites are microscopic (.2 microns to 20 microns), layered spheres containing alternating layers of multiple active ingredients. Spherulites may be made with positive or neutral electric charges, causing them respectively to attach to the negatively charged surface skin and hair or to penetrate into the various skin structures.
A second generation of dermatological shampoo products incorporating spherulite technology has been introduced: Hexadene® for fungal and bacterial skin infections, Pyoben® for deep skin infections, Sebolux® for keratoseborrheic problems and Allerseb-T® for greasy keratoseborrheic conditions.40 We expect these products to be a godsend to anyone suffering the trials and tribulations of owning a dog with chronic skin problems.
