Chronic kidney disease in dogs: real veterinary cases
Chronic kidney disease in dogs is most often a disease of older animals — gradual loss of functional nephrons over months to years, with the body compensating until ~75% of kidney function is gone. Early signs are subtle: a little more thirst, a little more urination, mild weight loss, decreased appetite. By the time obvious signs appear (vomiting, bad-breath uraemia, oral ulcers), CKD is well established.
Modern management has changed the picture dramatically. SDMA picks up declining function much earlier than creatinine; the IRIS staging system gives a clear treatment roadmap; renal diets remain the single best-evidence intervention; and managing proteinuria (with ACE inhibitors or telmisartan) and blood pressure prolongs comfortable life by months to years.
What vets typically check for
- CBC + chemistry + SDMA + urinalysis with USG; urine protein:creatinine ratio (UPC).
- Stage by IRIS criteria (creatinine, SDMA, USG, UPC, blood pressure).
- Blood pressure measurement — canine CKD commonly causes systemic hypertension.
- Phosphorus-restricted, high-quality-protein renal diet is the cornerstone of long-term care.
- Manage proteinuria (benazepril, telmisartan), phosphorus (binders), nausea (maropitant), and any UTI.

- Perioperative acute kidney injury in dogs undergoing elective desexing surgery.
Veterinary anaesthesia and analgesia · 2026 · Australia
Twelve dogs developed acute kidney injury (AKI) after undergoing elective desexing surgery, which includes procedures like castration and spaying. The study involved 165 dogs, and symptoms of AKI included decreased urine output in some cases. The researchers found that hypotension (low blood pressure) and being female were linked to a higher risk of developing AKI. While most d
- Presumptive Congenital Unilateral Renal Agenesis With Contralateral Dysplasia/Hypoplasia in a Golden Retriever.
Veterinary medicine and science · 2026 · Australia
A 4-year-old Golden Retriever was brought in for frequent urination, excessive thirst, loss of appetite, and urinary incontinence. Tests showed serious kidney issues, including a complete absence of one kidney and severe problems with the other. The dog initially improved with supportive care, but unfortunately, its condition worsened over the next few weeks, leading to the dif
- Supplementation with(SF68) and its association with biochemical parameters and inflammatory biomarkers related to renal impairment in dogs with chronic kidney disease.
The veterinary quarterly · 2026 · Spain
A group of dogs with chronic kidney disease (CKD) received a probiotic supplement called SF68 for 60 days to see if it would help their kidney function. The dogs that took the probiotic showed lower levels of certain harmful substances in their blood, which can indicate kidney problems, compared to those that received a placebo. Additionally, the probiotic group did not experie
- Urine protein electrophoresis analysis in dogs with systemic inflammatory response syndrome.
Journal of veterinary internal medicine · 2026 · South Korea
A group of dogs with systemic inflammatory response syndrome (SIRS) showed higher levels of certain proteins in their urine compared to dogs without SIRS. This study found that measuring the ratio of low molecular weight to high molecular weight proteins in urine can help veterinarians identify early kidney damage and predict outcomes for these dogs. The results suggest that th
- Chronic kidney disease in a dog with hematologic and cardiovascular alterations: A case report
Open Veterinary Journal · 2026 · LY
An 11-year-old male mixed-breed dog was brought in after showing signs of lethargy and not eating for three days. During the vet visit, the dog had a low heart rate but normal breathing. Tests revealed that he had chronic kidney disease (CKD), a common condition in older dogs that leads to a gradual loss of kidney function. Early diagnosis is crucial for managing CKD effectivel
- Evaluation of urinary amylase to creatinine ratio alone and in combination with urinary electrophoresis as a marker of renal damage in dogs with leishmaniosis undergoing conventional anti-Leishmania treatment.
Research in veterinary science · 2026 · Italy
A group of dogs with leishmaniosis, a disease caused by parasites, was tested for kidney damage using a urine test that measures the ratio of amylase to creatinine. The study found that this urine test could help identify kidney problems at diagnosis and track recovery after treatment with medications. In particular, dogs with certain types of protein in their urine showed sign
Frequently asked questions
- Is high protein bad for kidneys?
- Long-time myth. Healthy kidneys are not damaged by normal protein. In CKD, the issue isn't protein quantity per se — it's restricting *phosphorus* (which often correlates with protein) and choosing high-biological-value protein. That's why a veterinary renal diet, not a generic "low protein" food, matters.
- Are subcutaneous fluids at home worth it?
- In IRIS stage 3-4, yes — daily or every-other-day subQ fluids dramatically improve comfort, reduce dehydration-driven azotaemia, and most owners learn the technique quickly. They're less commonly needed in stage 1-2.
- What's the prognosis?
- Highly stage-dependent. Stage 2 dogs frequently live 2+ years with appropriate care; stage 4 dogs usually have weeks to months. Catching CKD via routine senior screening (SDMA) before clinical signs is the single biggest opportunity to extend good-quality time.
