We have a 6 year old male JRT neutered trial dog. For years when he runs a lot we see blood in his urine. Happened first a vets being boarded where he ran free all the time. After vets checks we found the hard running forces blood from the mussels and into the kidneys. He's always clear the next day. He's not a racer but when we let him race at some trials we occasionally see blood in his urine but it always clears within a day.
