I have a male chocolate lab who's about to turn two in February. There's nothing wrong with him, he's extremely healthy, well muscled (as he is a hunting dog) and very lively. My dog tends to sneeze a lot when he's rolling around on his back, or occasionally if he's super excited, but last night he did something really weird. I glanced over at him after he did this really big sneeze, not really thinking anything, but then all of the sudden he got up, with a funny look on his face. One eye was squinted shut and the other was wide open, and his mouth was all contorted. He tried to take a step and then started sneezing all over the place. It sounded really painful and forceful, and his expression looked like he was in pain when he looked up at me. He walked into the kitchen, practically sneezing his face off with every step, and that's when I noticed the blood. He was spraying pretty decent sized splatters of blood all over the floor. It wasn't excessive, like he was bleeding his brain out or anything, but it was enough to make me worried. I put the dog outside and called my parents over, but they said it was nothing, just a bloody nose. To be honest, they're a little inconsiderate of our animals, though. I glanced back out and my dog seemed fine, like nothing had happened. He looked a little shaky, but was wagging his tail and busting on in like it had been a wonderful day. I gave him a treat to get the incident out of both of our minds.
But just a short while ago, I looked up the incident on Google. Another person had asked a similar question, but their dog was older, and it had been more blood. But the thing that worried me is that a few answers said it may be a cancer tumor, or something dangerous of the sort. My dog's not even two yet, and he's like my little furry brother, so I would hate for anything to happen to him. Is this sneezing okay?
