get it checked out by a vet asap.

ideally you should not let it around your other dogs. My GF is a vet and see stuff like this all the time where the "stray" is carrying all kinds of diseases in fungal stuff in their lungs and spreads it to your other pets.

so what you feel like doing is a good thing it may cost you high vet bills or losing one of your other pets taking one in off the street without stopping at the vet's office first

Speaking of Pits, my one time room mate brought one home.
It was the most loving puppy and the only dog I've ever seen a dog actually bury a bone.

I ended up giving him away to a friend a few years later and the fucker killed his goat and most of his chickens.

It is an immensely grateful dog...that is what kind it is.  It looks like a pit bull/staffordshire terrier mix.    If you are wise enough to keep it, you will have one of the most loyal dogs on this planet.  Dogs never forget who saved their life.  

I would name it "Delta" after a very famous dog.  I'll look up the story, and come back and edit this post to add the story of Delta to it.

Here is the story of Delta:

In the year 79 A.D. there was a cataclysmic volcanic eruption of  Mount Vesuvius near the ancient city of Pompeii. Pompeii was a large trading port and home to many thousands of people. Everyone in and near the city of Pompeii at the time of the volcanic eruption perished on that fateful day so many centuries ago. The city was discovered under many feet of earth and volcanic ash.

What was eerily unique to this discovery was that the bodies of all the victims decomposed in the packed sediment which left a hollow cavity freezing in time the moment of there deaths, in a sort of 3 dimensional negative image. When another hollow cavity was discovered a cast was made by filling the void with plaster, creating an impression of the last moments of life for another soul. While archaeologists were making plaster casts of these cavities Delta was discovered. The cast of Delta’s body was found lying over the body of a young child. Also found in the bottom of this hollow cavity was a silver engraved collar with the dogs name “Delta” the collar also said that the dogs owner was named Severinus and that Delta had saved his life on three separate occasions

The first time Delta had pulled him out of the sea and saved him from drowning.
The second time Delta had defended Severinus when she fought off 4 attackers who had tried to rob him.
Third she had defended him from a wolf that tried to attack him somewhere near the city of Herculaneum.

Delta the hero dog tried once more (in vain) to save the life of a child, in all likely-hood the child Delta sacrificed her life trying to protect was the sibling of her owner Severinus. Delta may have been unable to save the life of that child but she gave her life trying and even with her dying breath Delta never once thought of herself.

You are very fortunate to have been chosen by this dog.  I accepted a dog that chose me once, and it was indeed a terrific decision.  I was looking at some registered border collie pups in a whelping pen when one of the dogs from a previous litter came up beside me, looked at me, gave me a sniff, and leaned against my leg.  I moved, and the dog moved and again leaned against my leg.  The next time I moved, the dog did the same thing and the breeder said "It looks like you have been chosen by a dog,  rather than you doing the choosing".   So I accepted the suggestion and he turned out to be an absolutely wonderful dog for the next 14.5 years until he went to the rainbow bridge.   I still miss him.

I sure hope you take the hint that the universe has given you.
