Scented shampoos formulated for dogs are fine, but your dog may have a preference for a particular scent. My dogs could not tolerate the smell of Chris Christensen's Day to Day products.
How old is Teppi? You might have to work with her, train her to accept grooming. Go slowly, and be patient, calm, confident, and reassuring. Talk to her, tell her what you are going to do, praise her when she is calm, and offer treats when she behaves correctly.
Work on grooming when she worn out after a play session or a walk. Don't attempt it when she is full of energy. Make grooming a relaxing and pleasant experience. I incorporate a lot of massage into the bathing and combing process.
Careful with water and shampoo near eyes and ears. Be sure to rinse very well to make sure nothing is in the eyes.
Hope some of this helps.
