- Chosen by Voters No more often than absolutely necessary. Bathing a dog strips all the oils out of their skin and dries their coat as well. So, bath him only when you have to, use dog shampoo, luke warm water and make sure to rinse very, very well to get all the shampoo out. Then towel dry and keep him in the house until he's entirely dry because they get very cold when wet. 5 years ago 67% 2 Votes 1 person rated this as good
