I'm sure this has probably been talked about hut i haven't seen it so fuck it.
Not a lot of people seem to understand that the Stark children finding Direwolves isn't just for something cool or to show their personalities and stories. It also is a clue to the fact White Walkers are back.
Let me explain. Animals understand danger. They know when a flood is about to happen, when an earthquake, even when a volcano is gonna erupt. Direwolves would feel the shift of when the White Walkers came back. And if them being animals and animals being infinitely smarter than most people isn't enough how about this. Direwolves are considered magic in Asoiaf lore. Starks were said to be able to shape shirt into a direwolf or even take over their direwolf. We know this now as warging. This is why House Bolton has a flawed man as their house signal. They would take Starks and flaw them so the beast would escape them. Obviously this is why they don't have a great relationship with the Starks.
So yeah, Direwolves are magic. But you may wonder how this all adds up.
Ned says "no direwoldlf has been this far south in a hundred years." (Also i may have worte the quote wrong don't come for me). So we know Direwolves don't come south, or past the wall in this case. So why would they be there? To me this is a sign they knew the white walks were back and the mom was trying to save her pups. Only to die from a antler (yet another foreshadow because Ned goes south for Robert only to die trying to keep Roberts bloodline on the throne).
All in all, that scene has so much foreshadowing in it. It shows the pups without a father (strange for wolves). A dead mother. And six pups completely lost.
