I have a dog (Maggie), she has some kind of weird smell from her anus. Its like a yellow pale (smells something like puss). But, she is all fine with food, going for her toilets and does not seem to be in discomfort. I am abit worried as the smell was there for almost 3 weeks plus.

Poor Maggie. There is a good chance this is the discharge from her anal glands. Dogs has 2 glands, one on each side just inside of their anus, that usually naturally express when they have bowel movements. Unfortunately, some dogs do not always express these and they will get full. Then they will accidentally express them by scooting their booty, licking back there, when they get frightened, or just because they get too full. I would have your vet’s office try to express her anal glands and you may need to give her a bath to see if that gets rid of the smell. Some dogs need regular expressing every 4-8 weeks. Most vet clinic do this for a small charge or even for free. You can also have your vet show you how to do it at home but I must warn you, it is a nasty job. :) I hope this helps!
