Why Is My Dog´s Urine so Dark?
If you are out for a walk and notice that your dog´s urine is not yellow, you need to find out why as soon as possible. Maybe it will be no big deal, and you will find out that your dog has a mild infection or her new diet has some strange red dye.
It can be a lot more serious. If you notice some of the other symptoms I describe below remember them and when you take her to your vet you can find out what is wrong.
In my experience, many problems can be dealt with easily if taken care of right away. A tumor on the bladder wall can be removed, but if left for months most of the bladder will be lost and the dog would probably end up being euthanized.
Dark urine can be an early symptom of many problems. If you do find out that your dog is healthy, all of you can be happy
Some common causes of dark urine in dogs
Urinary tract infection
Liver disease (hepatitis from infection, poison, cancer)
Blood loss into the body
Muscle damage (like a car accident)
Kidney or bladder stones
Vaginal or prostate infection or cancer
Some types of dyes in the dog food
Reasons for Some Changes
- Blood clots: If you see fresh blood and small blood clots it can be caused by an infection of the kidneys or bladder, kidney or bladder stones, or a tumor growing in those areas. If your dog is still intact she may pass a blood clot when she is in heat but it is not from the bladder.
- Black urine: If the urine is black instead of just dark that can be another sign of blood. It usually indicates that more blood is being lost.
- Clear urine: If your dogs urine is clear, and not yellow like normal urine, that incidates he is not able to concentrate urine. Have it checked as soon as possible because dilute urine can be a sign of many other health problems, like diabetes, that need to be treated.
What Else to Look Out For
Dark urine is not really the disease that is hurting your dog; it is just one of the signs to look out for when your dog has a problem. If you notice these other symptoms it can help your vet diagnose your dog´s problem quicker, and with less testing. If your dog:
- Is having a hard time urinating it can mean a problem with the bladder, urethra, or prostate
- Is drinking excessive water, many systems need to be looked into. One type of hormonal disease causes a dog to become dehydrated even when drinking a lot
- Has pale or yellow gums she may have blood loss or destroyed blood cells somewhere in her body
- Is weak or has pain in her back or legs it may mean that she has muscle damage
Other Tests Your Dog Might Need
The first part of your dog´s visit to the vet will be a physical exam. If she is anemic her heart may be very fast, if she has a bladder stone it may be large enough to be felt during the exam, or she might even wince when her muscles are palpated during the exam. A female dog might have a vaginal discharge, or an older male dog might have a swollen prostate.
Expect at the very least that your dog will need a urinalysis (a microscopic examination of her urine), a complete blood count, and a blood chemical analysis to check her liver, kidneys, and other internal organs. If you hesitate because of the costs, remember the love she provides you every day and do your best to support her now that she needs you.
Besides these basic tests, some dogs will also need:
- X-rays to check for any stones in the bladder
- Ultrasound to check the kidneys, liver, and bladder wall for tumors
- Laparoscopic exam and biopsy
Will My Dog Get Better?
Your dog has an excellent chance of getting better, but her chances really depend on what the cause is and how soon you have her checked out. If she has dark urine secondary to muscle damage, the problem will clear up as soon as the muscle heals.
A liver disease, especially cancer, is a more serious problem. Getting a diagnosis early will help in many cases.
It is difficult to say how things will turn out until the cause of the problem has been determined. I have read a very popular web sites that recommends you take a “wait and see” attitude towards your dog´s health. This is wrong. If your dog has dark urine, find out what is wrong today!
