<human>: I have two Shih-tzus (male and female). I try to bathe both of them twice a month and get them groomed every two to three months. My female's fur stays pretty clean and she doesn't usually smell too bad. My male, however, likes to lick himself...a LOT. After a week of bathing, he already smells bad and feels somewhat greasy to touch. Is this simply a case of needing to bathe him more than I bathe her, or is there some way that I can keep him cleaner for longer. Any tips on breaking his habit of licking himself profusely?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Male dog smells bad, but is on the same bath/grooming cycle as female, who doesn't smell bad. Should I bathe him once a week or are there solutions to get him to stop licking himself?
