Can anyone give me some advice regarding the blood in my bull terriers urine? She is due to come into season but this is the first time (she is now over 10 years old) that I have noticed so much blood and its really red....I would go as far as saying there is more blood than urine....she is eating ok, drinking plenty of water, looks ok etc but its a bit of a worry....she is also going to the toilet quite a lot and only a few drops of bllod/urine are coming out....any ideas please
