Oliguria, also related to anuria, is a decrease in the volume of urine produced. The difference between oliguria and anuria is that anuria is used to describe instances where the kidneys do not produce urine, while oliguria simply refers to a decrease in urine production (not necessarily at the fault of the kidneys). Oliguria is most likely related to renal function, as opposed to anuria, which is related to kidney function. Anuria could occur as the result of decreased renal function, though it is usually linked to obstruction of urine outflow or problems in the urinary tract. Symptoms include dehydration, shock, loss of appetite, and heart disease. Treatment varies depending on the underlying cause of the oliguria, but can include IV administration of fluids, medication, or surgery. Prognosis relies largely on the underlying cause of the condition.
Oliguria is a decrease in the body’s urine production, typically linked to problems with renal functionality. It is related to anuria, which is where the kidneys don’t produce urine, typically linked to obstruction or urinary tract problems.

Types
Physiologic oliguria occurs when the kidneys are saving more water than normal (as opposed to disposal through urination) in order to achieve normal levels of body fluid balance. When physiologic oliguria is the cause, animals will form small volumes of urine with high levels of specific gravity (the ratio of density of the urine to the ratio of a reference substance) and high osmolality (concentration of urine expressed as total of solute particles per kilogram). This is common in animals with prerenal azotemia (increased levels of nitrogen in the blood caused by a lack of blood flow to the kidneys; it is the most common cause of acute renal failure). Prerenal azotemia is typically caused by abnormalities that reduce renal perfusion with blood (e.g., limit blood flow), such as dehydration, shock, and heart disease. If the cause of prerenal azotemia is removed quickly, the kidneys will likely return to normal functionality. However, if the cause remains, primary ischemic renal disease may develop.
Pathologic oliguria is when the body does not have enough urine available for the body’s normal excretion of waste (through urination). The threshold for diagnosing pathologic oliguria is less than 0.5 ml/kg/hr. In dogs who are rehydrated and have acute renal failure, concentrations between 0.5 ml/kg/hr to 1.5 ml/kg/hr are indicative of relative oliguria. If infusion of fluids through IV results in excessive urination, the oliguria likely has a prerenal component. Pathologic oliguria may develop during early stages of renal failure as the result of generalized ischemic (resulting in restriction of blood supply to tissues) or nephrotoxic tubular (death of tubular epithelial cells in rental tubules of the kidneys) disease.

There are a number of different diseases that can cause oliguria in dogs. Some of these diseases include:

It is important to advise your veterinarian of recent behavioral changes you have seen in your pet, as well as the reasons for your concern that have led you to the visit. Any information you can provide will lead to a quicker diagnosis. Listed below are the tools that may be used in the diagnostic procedure.

Oliguria and anuria are serious issues and if there are symptoms of these conditions, you should seek veterinarian advice and medical treatment immediately. Treatment varies depending on the underlying cause of the oliguria. Possible treatments your veterinarian may employ include:

Post-treatment recovery and management depend largely on the underlying cause of the oliguria. It is important that urination is monitored to ensure that recovery is going smoothly. A catheter may be used through the recovery process to measure the volume in the bladder. Your veterinarian can advise best practices for catheter implementation and additional monitoring.

There are various causes for the symptoms which you described, especially in an older dog which would have a higher risk of cancer, heart, kidney and liver disease. There is a chance that Cozi is in pain; the usual signs of pain in dogs are crying, shaking, tenderness, increased heart rate, increased breathing rate (panting), behavioural changes (more aggressive or even depressed), changes in posture, loss of appetite as well as loss of bowel and urinary control. If you notice any of these signs (they wont all be present in each possible condition), visit your Veterinarian. Regards Dr Callum Turner DVM
