A good rule of thumb for bathing your dog is every 6-8 weeks using a dog shampoo and / or conditioner. Never use a people shampoo or conditioner because animals have different skin glands than humans. Generally, felines may be bathed every two months and ferrets may be bathed every 2-3 months. But remember, every pet situation is different. Age and type of your pet makes a big difference on how often is too often for bathing, or whether they should even be bathed at all.
Why is bathing too often a concern? Because the natural oil of our pet’s skin and fur is stripped away during a bath. Pet skin problems may occur due to the dry skin and coat from bathing too often.
