Green urine is seen when Pseudomonas aeruginosa grows in the urine, or when bilirubin urine is left for too long and oxidizes to biliverdin. Light green urine is common after taking a large amount of anti-inflammatory drugs. When the dog's urinary tract is infected with Pseudomonas aeruginosa, the urine will turn green due to the growth of Pseudomonas aeruginosa, and the dog will experience urinary tract itching. The dog's body produces abnormal bilirubin. Due to excessive biliverdin in the body, the urine will turn green.

Green urine in dogs may be caused by drugs. If your dog has been injected with drugs or taken drugs recently, you can ask your pet doctor whether the side effects of this drug can cause green urine. It may be that there is a disease in the colon and the bilirubin is oxidized and turns green, so the urine is green. You can go to the hospital for intestinal anti-inflammatory treatment.
