Plain-English summary
A group of puppies from two litters, including Boxers and Finnish Harriers, were found to have severe increased thirst and urination. Four of the puppies were examined by a veterinarian, who performed blood tests and urinalysis, and found that three of them had kidney changes consistent with renal dysplasia (a developmental kidney disorder). This condition may have caused their kidneys to not respond properly to a hormone that helps control urine production. Interestingly, some puppies showed no symptoms at all, even though one had the same kidney issue found during a postmortem exam.

Abstract
Puppies from two litters of dogs were found to have severe polyuria and polydipsia. Four of the dogs were investigated by means of clinical examination, haematological and biochemical analysis, and urinalysis. A modified water deprivation response test was also performed in two of the dogs. Renal changes on postmortem examination in three of the dogs were found to be consistent with renal dysplasia. A possible explanation for the finding of hyposthenuria and the extreme polyuria and polydipsia in association with renal dysplasia may be lack of response to antidiuretic hormone owing to anomalous maturation of the renal tubules. Six other puppies from the two litters of dogs did not show any clinical signs of polyuria and polydipsia, although postmortem examination in one of them also revealed renal dysplasia. The clinical features of renal dysplasia may therefore vary greatly between individuals.
