Depends on the individual dog as well as diet. Personally, my Boxer eats a good quality food and gets a fish oil capsule twice a day so he doesn't shed very much at all. I also take the Zoom Groom brush and take 2-3 minutes and brush him 1-2 times per week which probably helps too. And I bathe either when dirty or every 2-3 months whichever comes first.
However, I had a thicker coated Boxer female, now she also did not shed much but she had a thicker coat and different hair texture.
A lot of it really depends on the food fed, supplements given, and climate, but on a whole my Boxers have never shedded a ton and didn't require intensive brushing/grooming. Baths I do at home with the garden hose, takes me 5-10 minutes, they air dry and are good to go.
