Chronic kidney disease (CKD) is when dogs’ kidneys slowly stop working well. They can’t clean the blood like before. This isn’t the same as kidney injuries that happen all of a sudden. Many things can cause CKD, including infections, accidents, genes, medicines, poisons, cancer, and old age sickness. Dogs with early CKD might drink and pee a lot.12
When CKD gets worse, dogs might feel very tired, throw up, have diarrhea, and lose weight. To find out if a dog has CKD, vets do pee and blood tests. They check how well the kidneys work and how bad the CKD is. Finding and treating CKD early can help dogs live well for a long time.12
Key Takeaways:
- Chronic kidney disease (CKD) in dogs gradually impairs the kidneys’ ability to filter waste products from the bloodstream.3
- Early signs of CKD include increased thirst and urination, while advanced stages may cause lethargy, vomiting, diarrhea, and weight loss.3
- Diagnosis involves urine and blood tests to assess kidney function, and early detection and treatment can significantly improve a dog’s quality of life.3
- CKD affects up to 10% of dogs and can be managed with regular monitoring and appropriate care.1
- Treatment options for CKD include dietary changes, fluid therapy, and medications to manage symptoms and slow disease progression.12
What do the kidneys do?
The kidneys are crucial for a dog’s health, doing many important jobs. They filter the blood, getting rid of waste and toxins. They also keep essential minerals like potassium and sodium in balance, save water, and make urine.
Filtering the blood is a key job of the kidneys. They take out waste made by the body’s metabolism. This stops harmful substances from building up in the blood. The kidneys also manage the body’s water levels, affecting how much water is kept or becomes urine.
Kidneys are important for keeping electrolyte levels right, which cells need to work properly. They adjust the amounts of key minerals like potassium and sodium. This helps the body stay healthy.
Producing urine is another critical role of the kidneys. It’s how waste and extra stuff leave the body. This process keeps the body in a stable state, vital for good health and function.
In summary, the kidneys are essential for handling waste, keeping fluids and electrolytes balanced. They are key to a dog’s good health.

Understanding chronic renal failure
Chronic renal failure (CRF), or chronic kidney disease (CKD), happens when kidneys can’t clean the blood well. It doesn’t stop urine production. Despite making a lot of urine, the body’s toxins stay put. Kidney damage slowly develops over months or years before symptoms appear. Age plays a big role in CKD, especially as dogs get older. Small breeds often show kidney disease signs by ten to fourteen years old, while larger breeds might face it by seven.
Evidence-based facts:
- More than two-thirds of a dog’s kidneys must fail before symptoms of chronic kidney disease appear. This suggests the illness progresses silently for a long time3.
- Small dogs usually start showing kidney disease signs between ten to fourteen years. Large breeds can have symptoms as soon as seven years old. This shows a relationship between a dog’s age, size, and the beginning of kidney issues3.
Chronic renal failure in dogs is a complicated issue that needs close watch and control. Catching the disease early and starting treatment quickly are crucial. They help improve life quality for dogs with CKD. The following part will cover what symptoms to look for. This helps catch the disease early for better treatment results.
Recognizing the clinical signs
Dogs with early-stage chronic kidney disease (CKD) tend to drink more water and urinate more. This is because their kidneys are working harder to make up for lost function3. As CKD gets worse, you might notice your dog doesn’t want to eat, feels tired, or gets sick more often. They might also have mouth sores3.
To find out if a dog has kidney disease, vets do two key tests. They check the dog’s urine and blood. These tests show how well the kidneys are working3.
Diagnosing chronic kidney failure
To find out if a dog has chronic kidney failure, doctors do two main tests. They look at the dog’s urine and blood. These tests help understand how well the kidneys are working.
One of the first signs of kidney trouble is when a dog’s pee is too diluted. This test, called USpG, checks how concentrated the urine is. If it’s not concentrated enough, it could mean the kidneys aren’t working right3.
Doctors also check if there’s too much protein in the urine. Healthy kidneys keep important proteins in the blood. But when kidneys are sick, protein can leak into the urine. This is a sign of kidney damage3.
Blood tests help too by looking at waste in the blood. BUN comes from the liver, and creatinine comes from muscles. If these are high, it means the kidneys are struggling3.
Recently, a new marker called SDMA is used for spotting kidney disease early in dogs. SDMA levels rise before creatinine levels do. This helps start treatment early3.
Additional Diagnostic Tests
Sometimes, dogs might need extra tests to check their kidneys. These tests show how the kidneys look and work, helping decide the best treatment.
An ultrasound can look at the kidneys’ size and shape. It can find problems like cysts or blockages. It’s useful for figuring out the right way to help the dog.
Some dogs may also have their blood pressure checked, along with other tests. These tests can find issues caused by kidney disease. They help doctors make better treatment plans.
Early Diagnosis and Treatment
Finding and treating kidney failure early is key. Dogs can live well for a long time if the disease is caught and managed early3.
Starting treatment right away helps slow the disease down. The main goals are to keep the kidneys working, ease symptoms, and fix what’s causing the problem.
The first step in treatment often involves clearing the kidneys with lots of fluids. This can make the kidneys work better. Outcomes vary: some dogs get better for a while, some temporarily, and some might not improve3.
Specialized Diets for Dogs with CKD
Food plays a big part in treating dogs with kidney issues. There are special diets made just for them.
These foods have less protein and phosphorus. They also don’t make the urine acidic. This helps the kidneys work less hard.
Some well-known kidney diets for dogs are Hill’s Prescription Diet K/D, Purina Veterinary Diet NF, and Royal Canin Renal Support. They meet the special nutritional needs of dogs with kidney disease and taste good too.
Treatment options for CKD in dogs
Treating chronic kidney disease (CKD) in dogs focuses on easing symptoms and slowing the disease. The goal is to make life better for these animals. There are two main steps in treating CKD, each targeting different parts of the illness.
Phase 1: Flushing the kidneys and restoring function
First, treatment starts with diuresis. This uses plenty of IV fluids to cleanse the kidneys and blood.3It helps get rid of harmful toxins and aids kidney cell recovery3. Success can vary from temporary improvement to no change in kidney function3.
Phase 2: Managing and maintaining kidney function
The next step focuses on disease management and keeping the kidneys working. It covers a variety of treatments such as:
Specialized diets:
Kidney-friendly diets are key for managing CKD. Foods like Hill’s Prescription Diet K/D and Royal Canin Renal Support are low in protein and phosphorus. They lighten the kidneys’ load and help balance the body’s systems3.
Phosphate binders:
Phosphate binders control high phosphorus levels in the blood. Compounds like aluminum hydroxide reduce the kidneys’ stress and halt further damage3.
Home fluid therapy:
Home fluid therapy, or giving fluids under the skin, fights dehydration and clears out kidney toxins. It’s a hands-on way to support kidney health3.
Proteinuria therapy:
Excess protein in urine, or proteinuria, often happens with CKD. Treatments like ACE inhibitors can help manage this problem3.
Treatments for CKD need to be tailored to each dog’s specific needs. Work with a vet to find the best approach3.
It’s crucial to check how well a treatment is working and make changes as needed. Regular vet checks, including blood work to watch kidney health, are key. With the right care plan and ongoing checks, dogs with CKK can enjoy better lives4.
Importance of diet in managing CKD
Nutrition is key in managing chronic kidney disease (CKD) in dogs. Special diets are made to help dogs with kidney issues. These diets have less protein, phosphorus, and acid, making it easier for the kidneys.
Studies show that diet changes greatly help dogs with CKD. A study5 found that dogs eating less protein were healthier than those on a high protein diet. This shows how important the right diet is.
“Moderate protein and phosphorus restriction reduced morbidity and mortality in beagles with induced CKD while high protein intake worsened clinical signs and increased death rates”
This tells us that dogs with CKD need a special kidney diet. Such diets are designed to give these dogs the nutrients they need while being easy on the kidneys.
A different study6 looked at dogs with natural kidney failure. Dogs on special diets lived about 13 months longer than others. Also, they were three times less likely to have uremic crises.
“At the end of a 2-year study, only 33% of dogs receiving the renal diet died from renal-related causes, compared with 65% of dogs receiving the maintenance diet.”
This proves the value of kidney diets for dogs with CKD. The right food can improve a dog’s life and even make it longer.
When choosing a diet for CKD dogs, talk to a vet. Diets like Hill’s Prescription Diet K/D, Purina Veterinary Diet NF, and Royal Canin Renal Support are often suggested. They’re made to help with kidney function.
These kidney diets also have less sodium. This helps avoid fluid buildup and eases kidney work.
Adding omega-3 fatty acids is a good idea too. They fight inflammation and help slow CKD.
It’s important to stick to the feeding directions and check with a vet for changes. This depends on the dog’s CKD stage and needs.
Summary:
Special diets help dogs with CKD by lowering protein, phosphorus, and acid levels. This makes the kidneys’ job easier and lowers toxin buildup. Research shows these diets lead to better health and longer lives for these dogs. Always consult a vet to choose the best diet for your dog.
Monitoring and prognosis
It’s key to keep a close eye on chronic kidney disease (CKD) in dogs. Regular checks help vets see how the disease is moving forward. This helps them tweak the treatment as needed. The International Renal Interest Society (IRIS) staging system is a trusty tool in this process.3 It checks things like serum creatinine and urine protein levels. These help figure out the CKD stage and plan the treatment.
How long dogs with kidney disease will live can depend on many things. Important factors are the disease stage, the cause of the CKD, and how well the treatment works.7 Even though CKD gets worse over time, finding and managing it early can really help. It makes life better for dogs with kidney disease.
Monitoring CKD in Dogs
Vets keep an eye on CKD by running blood and urine tests often. This lets them adjust treatment plans when needed. Urine tests look for early kidney trouble signs, like too much protein. Blood tests check BUN and creatinine levels to see how the kidneys are doing.3
“Regular checks help vets step in at the right time. This can make a big difference in managing CKD in dogs.”
Prognosis for Dogs with Kidney Disease
The future for dogs with CKD depends on different things. Being older can make CKD more likely, with over 80% of cases in older dogs.7 CKD moves at different rates for each dog. About half of the dogs will see their disease get worse, especially in the late stages.7
Some things, like high phosphorus levels, anemia, and being underweight, can shorten a dog’s life. Managing these well can make the outlook better for dogs with kidney disease.7
“Despite CKD progressing over time, quick and effective care can greatly improve a dog’s prognosis.”
Remember, each dog reacts differently to treatment. Right now, there’s no way to tell exactly how treatment will work out for CKD.3
| Factors Affecting Prognosis and Monitoring of CKD in Dogs | Statistical Data |
|---|---|
| Total number of dogs with risk factors for CKD analyzed | 545 dogs7 |
| Advanced age as a risk factor for CKD | 80.6% of cases7 |
| Progression of CKD during the follow-up period | 47.2% of cases7 |
| Serum symmetric dimethyl arginine (SDMA) differences | During early stages of CKD7 |
| Difference in survival curves between early and advanced CKD stages | Observed7 |
| Factors related to decreased survival | Hyperphosphatemia, anemia, low BCS7 |
| Comparison between arterial hypertension and renal proteinuria in survival rates | No significant differences7 |
Conclusion
Chronic kidney disease (CKD) is common in older dogs. They lose kidney function gradually. Spotting CKD early and starting treatment fast are key to help these dogs. Various statistical data8910 show how often CKD occurs in dogs. Urine and blood tests help find out how bad the disease is. Diets and treatments can slow CKD down and make dogs feel better.
It’s important to keep checking a dog with CKD regularly. The International Renal Interest Society (IRIS) system helps know the CKD stage. Life expectancy depends on many factors. But knowing the signs and treatments helps pet owners care for their dogs.
In the end, catching CKD early and taking care of it properly matters a lot for dogs. With the right support, dogs with CKD can still enjoy life. It’s all about teamwork between pet owners and vets to look after dogs with CKD.
