I don't think dark urine is normal at all and could be a symptom of liver disease, bladder infection or prostate problem. I would definitely get a urine sample and take it to the vet with you for a checkup.
From the web:
If your dog's urine is darker than usual, it could be an indication of blood in the urine. It's especially a concern if it's associated with a high temperature in the dog. A dog that squirts or dribbles his urine could have a bladder problem, or in males - a prostate problem. |
