Early Symptoms of Kidney Problems in Dogs You Should Not Ignore

Kidney disease in dogs is generally quiet and hidden enough to make it important for one to recognise the early symptoms of this illness in their pet. When one starts noticing the symptoms of kidney problems in their dog, the illness has already reached a considerable level of development. It is always found that the clinical symptoms related to kidney function in dogs usually become visible when about 75% of their functioning ability has been damaged. Three-fourths of its capacity have been damaged without one even knowing about it. It is thus important for all dog owners to detect such illnesses at an early age.

The guide helps owners recognise the symptoms of kidney problems in dogs. It also covers the causes, the stages, the diagnosis, and the role of diet in management.

What the Kidneys Do and Why Kidney Problems in Dogs Are So Serious

Before we talk about kidney disease in dogs, it would be necessary to understand the role of normal kidneys in their body.  Numerous functions are carried out by a dog’s kidneys at once. These include blood purification to urine form, electrolyte regulation, blood pressure regulation, hormone production, and red blood cells formation. Kidney failure causes all these activities to stop working.

There are two kinds of kidney diseases that dogs suffer from. Acute Kidney Injury (AKI) appears suddenly as a consequence of ingestion of some toxin or an infectious disease, and even as a result of physical trauma such as obstruction. It can be very dangerous to health and even deadly in some cases, but usually treatable. Chronic Kidney Disease (CKD), on the contrary, emerges slowly and cannot be reversed.

Early Signs of Kidney Problems in Dogs: The Signals Most Owners Miss

The early signs of kidney problems in dogs are frustratingly non-specific. These are the signs to take seriously, even when they seem minor:

Coat Changes and Weight Loss

The development of a somewhat dull coat, with reduced shine and extra shedding, along with a hint of being scruffy, accompanied by very slight weight loss, which can only be detected through the vet’s scales, is one more sign that indicates the onset of kidney disease in dogs. It is not noticeable enough to raise concerns by itself.

Excessive Urination and Thirst

It is one of the first symptoms of kidney problems in dogs, and so distinctive that it requires a veterinary appointment immediately. In case the kidneys stop concentrating urine effectively, the body makes an attempt to produce more of it. As a result, dogs have more frequent and copious urination and, thus, they become thirsty in order to keep balance.

Unnoticeable Changes in Behaviour

A dog with the first stages of CKD looks slightly lethargic compared to what it usually is. For example, it may show some lack of enthusiasm during walks, greet its owner slowly, and rest most of the time. This behaviour change cannot be regarded as an obvious sign because it is very easy to explain its occurrence.

Changes in Urine Appearance and Smell

The urine of a dog suffering from the early stages of kidney disease will appear lighter or even colourless, without much odour or with a faint ammonia-like odour. This is because there will not be an effective concentration of urine by the dog’s kidneys. In case you note that your dog’s urine resembles water, this is something that should be reported to your vet.

Symptoms of Kidney Problems in Dogs: Early vs Advanced

Here is a side-by-side view of how the symptoms of kidney problems in dogs change as the disease progresses. The left column is where intervention is most effective. The right column is where the disease is already significantly advanced:

What Causes Kidney Problems in Dogs?

Understanding the causes of kidney problems in dogs helps with both prevention and early detection, particularly for high-risk breeds and older dogs.

Degeneration Due to Ageing

One of the leading causes of CKD is degeneration due to ageing. It means that the kidney function naturally deteriorates with time in a canine body. Smaller breeds usually develop CKD at an older age of about 10 to 15 years. On the other hand, larger and giant breeds typically develop CKD much younger, about 5 to 7 years.

Breed Specificity

There is a list of breeds that have genetic predispositions to kidney diseases. Yorkshire terriers, Cavalier King Charles spaniels, boxers, German shepherds, Samoyeds, bull terriers, and shih tzu are considered the most frequent breeds of dogs with this health issue.

Exposure to Toxins

Acute kidney injury in canines can happen as a result of exposure to various toxins. Among those toxic substances known to cause acute renal failure, grapes and raisins are the most common. Even a small number of these products eaten by a dog may trigger renal failure. Other types of toxins include various medications, including NSAIDs (naproxen, ibuprofen, etc.).

How Kidney Problems in Dogs Are Diagnosed

In case you see some of the early symptoms mentioned above for canine kidney problems, the following diagnostic procedures are quick, easy and do not harm your pet:

• CBC – complete blood count test used to identify anaemia that occurs at the final stages of chronic kidney disease due to the inability of the dog’s kidneys to produce erythropoietin

• Biochemistry panel – includes measuring of creatinine, BUN (blood urea nitrogen), phosphorus, potassium and albumin in blood

• SDMA test – a sensitive test used to detect early renal issues, which identifies changes faster than creatinine does

• Urinalysis – determines concentration of urine, presence of protein loss, casts and infections in urine

• Protein-to-creatinine ratio test (UPC) – determines how many proteins the kidneys lose

• Blood pressure test – high blood pressure is both a symptom and a cause of kidney diseases in dogs

• Abdominal ultrasound – determines the state of the kidneys, presence of stones, tumours, or cysts

The Role of Wet Food and Moisture in Kidney Health

A diet high in wet food does not only ensure better palatability but is actually an important therapy for canine kidney diseases. While wet food has a much higher level of moisture than dry kibble (70-80% vs. 10%), the difference becomes very significant as it directly affects the way dogs urinate and the amount of waste product that is flushed from their body. It decreases the workload of the kidney, minimizes the chance of developing secondary urinary infections, which are very common among dogs with CKD.

When you notice any signs of kidney problems, serve Zoomies wet food as a main portion with added warm water. It is the easiest thing you can do daily and probably the best choice for your dog's kidney health. When you are dealing with dogs with diagnosed CKD stages 3 and 4, consult your vet about the need for a special diet in combination with Zoomies as a supplementary source.

How To Reduce Risk of Kidney Disease in Dogs: The Preventable Factors

You can’t guarantee your dog will never develop any kind of kidney issues, but there’s plenty you can do to minimise their risk or recognise problems in time:

• SDMA included in yearly blood tests – beginning from age 7 – starting from age 5 for large breeds and at-risk breeds

• Moisture-rich wet food as a base – adequate hydration is the primary dietary factor in preserving kidney function

• Freshwater should always be available – numerous water stations, daily cleaning, and changing water twice a day

• Proper oral hygiene – teeth brushing and annual professional cleaning to prevent bacteria from spreading to the kidneys

• Taking away the toxins – grapes/raisins, NSAIDs, antifreeze, and certain toxic plants must not have any access

• Evaluate your dog's overall body weight – obesity is a major risk factor for kidney diseases in dogs of all ages

Conclusion: Symptoms of Kidney Problems in Dogs

The signs of  kidney disease in dogs should be considered, although not alarming – increased thirst, loss of appetite, and slight indifference. None of them sounds like an emergency case, yet they all need to be carefully monitored.

It is important to know that kidneys are extremely robust organs capable of enduring injury until their capacity for coping with any harm is lost. Prevention involves regular blood tests once a year, the adoption of high-moisture feeding, and knowledge about behavioral peculiarities.

Help your dog stay healthy with Zoomies high-moisture wet food – 100% human-grade real meat, no preservatives whatsoever, and plenty of natural moisture.
