Bathing dogs with healthy skin and hair coat can interfere with the dogs natural protective oils and disturb the delicate balance of beneficial microbes that live on the pet’s skin.
However, dogs are notorious for getting into stinky things that most owners find repulsive. In these cases, bathing your dog periodically (a few times a year) with a mild doggie approved shampoo is not harmful.
On the other hand, some dogs need to be bathed on a regular basis (weekly to monthly) to help them combat harmful bacteria, yeast, or parasites. Allergies, thyroid disease, autoimmune conditions, metabolic diseases, and cancer can all alter the skin making frequent bathing with medicated shampoos a necessity for the pet’s comfort.
