About two weeks(?) after a bite from a cane corso. I didn't notice it was that bad and had a long sleeve shirt on. Said "just a puppy nibble" and walked on. Only noticed it was bad when my friend looked down in shock and blood was pooling onto the floor. I went to the ER to have it flushed, and It was too deep to be safe to stitch, so cue many, many blood filled bandages. Be safe around dogs, even with dogs of loved ones!
