it could just be down to hormones and if her coat is oily some shampoos dont rid the smell cos the oils dont lift . Saying that i wouldnt advise you to use anything strong as it may irritate her skin . I use sainsburys economy brand baby shampoo or johnsons baby shampoo. make sure the coat is soaking wet massage lots of shampoo into all the nooks and crannys and most importantly rinse thouroughly residue can cause irritation even if the shampoo was mild . And then a good towel down a damp dog smells quicker i often wash bedding at the same time so they dont pick odour up from blankets .
