Why is it dogs will do their business in front of people or other dogs? Have they no shame? Shouldn't you give your dog privacy?

I'm not sure pack animals have any sense of shame/privacy.  That, seemingly, is an exclusive trait of higher critters (e.g., us :-)).

now there is something to

 flip your flippers about.

You should have your dog poop in your own yard for your eyes and smell only.

I think it's funny (odd) that cats do have that sense of 'shame'.

cause they dont care about their privacy like people do

Poo is a big part of a dog's social life.  They check each other out by sniffing each other's butts.  They also roll in fresh dog poo.  Unfortunately the poo roller was my Sheltie, and just had to be the long haired breed that wanted to roll in it, yeah.  He finally gave it up when he figured out he was going to get a bath every single time he rolled in it.

An make sure it is wearing its panties before you go out ;-))

I find it amazing how so many people love dogs, but wont allow them to be dogs.
