Can you help me identify this lost dog?

I found him outside a few hours ago. I opened the gate and let him inside because it has been raining since yesterday and he is wet. His paws are still-like, I figure they must be freezing but he also limps a little. He looks like a big dog, it must be because of all that fur he has. His tail also looks naturally little. And I can see a collar but it’s buried beneath all it’s fur. I’ve been searching the interwebs myself to try to find his breed but I don’t know where to start from.
