I'm getting cold and hungry, but I need to find shelter first.
Poor dog, probably couldn't adapt.
So say this is was a pet put escaped his home and now is lost. He keeps on wandering around till he is in a cold place.
He doesn't know how he ended up in a snowy place but he's getting real cold and his paws are getting raw. He is getting hungry but he knows he needs to find food and a shelter.
On his way trough the forest, he stumbled onto a dog corpse that didn't look to old. He thought on his way by that the dog probably couldn't adapt to the cold and died. It appears that he has been feasted on by predators so I'll watch out for them tonight.
I've finally found my owners.
As he wonders around, he finds an abandoned so he thinks of it being his shelter for the night. He sees some animals living inside so he knows he has a sustainable food source.
I guess I have a shelter now and a food source.
As you can see, he has finally adapted to the wilderness, and getting food to survive.
After a bit of time, he found his owners and knows how to survive in the wilderness in case of an emergency.
