If you are feeding drying food, she may need more water to help digest it. Also, that breed is very energetic. Some dogs only seem to drink with owners present and drink very little in the day when alone. If it seems excessive (you are always filling up the bowl) give her 8 oz at a time and see how long it takes her to drink that and keep up with how much she consumes over a 24 hour period. You can then take that to your vet for them to check and do a urine sample or blood test to make sure there is no infection or diabetes.
