I don't do anal glands as a routine. I learned the hard way when I caused an impaction on my last great dane and she had chronic troubles for the rest of her life.
IF the dog is having troubles, I'll express them as needed. If not, I let nature take it's course. To be a little graphic, Hannah's glands express themselves freely each time she has a bowel movement, as do most dogs'.
Ears are wiped out as needed. Both of my dogs are swimmers, so it's something I do keep an eye on.
