I bath the bullies about twice a year but keep the girl and boy parts as well as ears and paws and faces clean with wipes and sometimes hibitane every few days. If they roll in stuff they get a wash but not a full out bath. But Buster gets a bum wipe every other day. Miss Tallulah not so much as she had her tail amputated because her tail and pocket caused so many problems early on. If they has a smell they would be bathed but with a clean diet and a little maintenance they seem sweet and clean.
