Yes i agree with Nonnie its does.Our bitch had cystitis after being in season 49days
Yes no joke 49days! ..She also had fresh blood in her wee and on the way to the vets she actually passed a crystal..They put her on anti-biotic's for 10days then we had to take her back, it wasnt clear so they put her on them for a futhur 6 days!!

Hope your girl is ok and good luck at the vets!
