My young dog, who is only 2 years of age, has just started to have great difficulty 'wee-ing' over the weekend & has had to be catheterised 3 times now to empty his bladder. His urine isn't too acidic or alkaline, tests negative for blood, or crystals or bacteria, a little protein in there but not so much that it worries the vet. He is desperate to go to the loo but just manages a dribble or two.....in an older dog the vet says she would immediately suspect prostrate trouble but apparently this is really rare in such a young dog & on palpation it feels normal size not enlarged. She has also ruled out stones in his urethra as she can pass the catheter very easily so there doesn't seem to be any mechanical blockage or excessive inflammation which has closed it down. He is currently on antibiotics & anti-inflammatorys but I just wondered whether anyone else has experienced such symptoms in a young dog? Any advice welcome.
