Seems ours get kinda oily after 4 to 6 months so they get the shower treatment 2 to 3 times a year. We are flea free, from day one (7 and 8 years respectively now) which is amazing considering we got ours 'used' (both were rescue dogs) so we don't flea dip or anything. They only get shampooed when they get too oily, or when they rolled in something. So how often is it recommended to bathe our hounds, and what do you use? We have some citrus shampoo, with of all things, a Beagle on the front of the bottle (we didn't pick that brand for that reason, no seriously, we didn't!) but it claims no harsh chemicals. Sure makes them soft for a good month or so. And they smell like oranges for a good day or two too!
