PINK RESCUES STRAY DOG FROM RIVER, SPENDS THOUSANDS

P!nk just came through with a canine Christmas miracle -- shelling out $5,000 to pay for emergency life-saving surgery on a puppy that had been tossed in the L.A. river and left for dead.

Sources tell TMZ ... P!nk was surfing the Internet recently, when she stumbled upon a story about a puppy that had been thrown off an L.A. overpass ... and suffered 3 broken legs when it landed in the L.A. river.
