A lot depends on what you are feeding your dog.... for instance, a dog on raw food will poo two very small firm poos a day, but if they are eating something like canned food plus mixer, they may do three or more large soft dumps instead.
As to wees, I think a dog should be let out for a wee whenever you can or whenever you think of it - they may not have a wee but like the chance to have a sniff about. And if you have trained a word for it, you can often encourage them to empty their bladder anyway which has a lot of other benefits especially when you may be travelling or staying in unfamiliar places.
Male and female are also different - I swear male dogs are totally hollow... they seem to be able to hold a tankfull for hours!!!!
