had this problem for the last season had the dog to 3 different vets ,still not 100% whats up with the dog,he gets 1 tablet a day which is methionine which is a sort of a yeast tablet and after he as been coursing he as to have 15ml of pot citrate which keeps the level of acid down.when the blood starts he has to have antibiotices and it stops it within days but its not a nice sight to see,but in your case it sounds like shes brused a kidney ,,good luck
