I bathe very frequently as well . I have 5 dogs ....the oldest is 11 the youngest is 3 months . I bathe Colby and Tia ( both longer coated dogs ) once a week to once every 10 days. I bathe the short coat chi's about once every 2-3 weeks . I bathe Calli about once a month . NONE of my dogs have ever had skin issues,dry skin,,dandruff ect . I bathe with Petsilk products which is healthy for their skin and coats. Every one of my dogs have beautiful coats .
I HATE doggy smell , and if you have dogs and they dont get bathed except every 2-3 months , they will have a doggy smell. I guess maybe some people are used to that ?? or doesnt notice it as much ?? I am just a fussy clean person and since my dogs sleep with me , they need to smell fresh and clean.
I think that its a personal issue and one that each person must decide how long they can go . Obviously if you are bathing frequently and your dog starts to have issues such as dry skin,,dandruff ect ........... than that particular dog may not be able to handle frequent bathing ....and you may not be able to bathe as frequently . But , if you are bathing frequently and are having no problems ...then its not a problem
