What is High Levels of Blood Nitrogen?
When your dog has high levels of blood nitrogen in his blood, it is caused by a buildup of waste materials, such as creatinine, urea, old cells, and food. There are four stages a dog goes through with this disease, which are:
Very Mild (Non-Azotemic) Kidney Disease
This is the beginning of the kidney disease and there are usually no physical symptoms in your dog. In fact, it will not even be found in blood tests yet because there is no damage to the kidneys to cause any clinical signs.
Mild Renal Azotemia
When there is enough damage to the kidneys that it causes few very mild symptoms and may only be found as a slight increase of nitrogen in your dog’s blood.
Moderate Renal Azotemia
At this stage, your dog’s kidneys have been damaged enough to cause both physical and clinical symptoms. At this stage, the damage done may be irreversible, but can be slowed or halted with treatment.
Severe Renal Azotemia
The damage to the kidneys at this point will be obvious. Blood tests will show elevated levels of creatinine, urea, and calcium. Urine tests will show an excess protein and increased urine specific gravity. Your dog will have most or all of the symptoms show below.
High levels of blood nitrogen is caused by renal azotemia, which is described as an accumulation of waste products in the blood. Symptoms commonly do not show up until there has already been some damage to the kidneys. The reason for this illness can range from many different things, such as the wrong kind of diet, infection, serious injury, urinary obstruction, acute and chronic kidney failure. There are four stages of azotemia, ranging from very mild to severe.

Diagnosis of High Levels of Blood Nitrogen in Dogs
Your veterinarian will need to know all of your dog’s medical history, what symptoms you have noticed, and when you noticed them. The veterinarian will do a complete physical examination of your dog, taking special notice to palpate the kidneys and abdomen. They will take your dog’s blood pressure and temperature before running some tests. Some of the tests they will need to do are:
- Urinalysis to check for anemia, specific gravity, white blood cell count, and protein levels
- Biochemistry to find levels of phosphorus, calcium, and the sodium to potassium ratio
- Clotting test to find your dog’s ability to stop bleeding
- CBC (complete blood count) measures all of the major types of blood cells, such as red blood cells, white blood cells, hemoglobin, and platelets
- BUN (blood urea nitrogen) to find the levels of nitrogen in your dog’s blood
- Digital radiographs (x-ray) of the abdomen
Depending on the outcome of these tests, your dog’s veterinarian may decide to do more tests, such as:
- Ultrasound
- CT scan
- MRI
- Biopsy of the kidney
Treatment of High Levels of Blood Nitrogen in Dogs
The first thing your veterinarian will do is to restore fluids in your dog and reduce the toxins in his body. Antibiotics or other medications may be given for the underlying problem such as kidney infection.The treatment will depend on the cause of the disorder and the test results. If the results show that your dog is in either stages one or two, your veterinarian will put him on a special diet designed especially for dogs with kidney failure. This diet is low in protein and sodium and high in omega 3 and omega 6 fatty acids. The food also has potassium citrate for acidity and lower phosphorous so these do not build up in the blood.
Special vitamin supplements will also be prescribed for your dog to help with weight loss and anemia. Your veterinarian will also prescribe a medication for hypertension, such as an ace inhibitor that will aid in slow down or even repair some kidney repair.
Your dog will have to go back to see the veterinarian every few months for blood tests and urinalysis. The veterinarian has to watch his protein levels so they do not get too low. Because the kidneys are needed to process medication, the veterinarian will have to be careful with what medication he decides to use. The unnecessary work for the kidneys may cause more harm than the not giving the medication.

The prognosis for high levels of blood nitrogen depends on the cause of the disorder and what stage it is in when found. If you follow the diet and other instructions that your veterinarian prescribes, your dog could live happily for several more years. You will have to keep track of how often and how much your dog urinates to check his kidneys’ function. Regular veterinarian care and blood tests every six months are essential to your dog’s health so be sure to keep all of your appointments.
