Most Labradoodle experts say that you should only bathe them every six to eight weeks as over-bathing can harm the quality of their coat. A little dirt can easily be brushed out of your pet's hair. That being said, if your pooch has been out rolling in something nasty, you should give them a good clean before they tramp the smell through your house. How often you bathe your Doodle will also depend on the type of shampoo you have. Mild, non-soap formulas are great for regular use and won't leave your Doodle's skin dry and their coat brittle. However, products that target specific issues are likely to contain stronger chemical ingredients and should be used more sparingly.
