Do they shed and how much grooming/bathing do they need?

Yes, this breed does have hair loss. If your dog is a house dog year round, you may have a some hair loss all the time and then a large blowing of coat in the late spring and late fall. A warm bath and a good brushing with a shedding blade will get most of it out over a few days. Generally if their living quarters are clean, likely a bath or two a year is all that is needed. Check their nails to make sure they don't get overgrown and the ears once a week for smelly ear yeasts. This is not a breed for someone with allergies.
