I used to bath morgan every week because her head hair looked greasy. However since i started using Milksheen regularly her head doesn't get greasy. the only thing i have to worry about is stinky beard and that usually is from her tear stains. so i just clean that up and give her beard a little cleaning and she lasts longer. hot or cold outside i bath her whenever she needs it. never had a problem with dry skin or freezing puppy feet
