Hmmmmm well so far Fiona has not been losing any hair. Maybe some when we take a bath. I say "we" because I am as wet as she is when we are finished. I bathe her once every 7 to 9 days though and feel that helps cut the shedding down. Of course she is only 3 1/2 months so maybe I have not hit the puppy peek of shedding yet?.
