My dog is a 5 lb, short hair chihuahua who spends most of her time inside, when we go for walks she doesnt usually get dirty. Depending on the area, her walks are both on and off leash. She does have a doggy odor which I find extremely pleasant! so I never get the urge to give her a bath. I did give her a bath yesterday (first in a long time) but that was only in hope of removing dead fur (I dont think it did much good). So am I ok or are baths a necessity?
