Renal Dysplasia in Dogs
Renal Dysplasia is a high-severity urinary condition that can affect dogs of all ages and breeds. Renal dysplasia is a hereditary condition where the kidneys develop abnormally, with immature or disorganised tissue. Affected puppies develop progressive renal failure at a young age. The severity varies from subclinical to fatal early-onset kidney failure. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Under 2 years. Early signs to watch for include failure to thrive, increased thirst and urination, vomiting, and poor coat. When treatment is required, costs are estimated at £1,000-£3,000/year depending on severity, location, and the specific intervention needed. Renal Dysplasia has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
Signs & Symptoms
The following symptoms are commonly associated with Renal Dysplasia in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.
- Failure to thrive
- Increased thirst and urination
- Vomiting
- Poor coat
- Stunted growth
- Signs of uraemia in severe cases
Treatment Overview
There is no cure. Medical management follows CKD protocols — dietary modification, phosphate binders, and supportive care. Many affected dogs are euthanised at a young age due to severe renal failure.
Typical onset: Under 2 years
Prevention & Screening
While not all cases of Renal Dysplasia can be prevented, the following steps reduce risk or enable earlier intervention:
- DNA test available for Shih Tzu and Lhasa Apso forms
- Renal biopsy of breeding stock in predisposed breeds before mating
Estimated Treatment Cost
Treatment for Renal Dysplasia is estimated at £1,000-£3,000/year, depending on severity, the specific intervention required, and your location. Costs may be higher for surgical procedures or ongoing management. Comprehensive pet insurance covering hereditary conditions is strongly recommended.
