Plain-English summary
A group of Estrela Mountain dogs, aged between four and twelve months, underwent tests to check for early signs of hip dysplasia, a condition that can cause joint pain and mobility issues. The tests included the Ortolani method and the PennHIP method, which helped predict the likelihood of developing moderate to severe hip dysplasia later in life. Results showed that the PennHIP method was particularly effective in accurately identifying dogs at risk. This means that owners can get a good idea of their dog's hip health before they turn one, allowing for early intervention if necessary.

Abstract
OBJECTIVES: To determine the reliability of early passive hip laxity examination in predicting moderate and severe hip dysplasia. METHODS: The passive hip laxity of 104 Estrela Mountain dogs was evaluated using the Ortolani method, conventional hip-extended radiography and the PennHIP method, when the animals were between four and 12 months of age. After the age of one, dogs were re-examined for hip dysplasia using the Fédération Cynologique Internationale scoring system. The passive hip laxity results were subsequently compared with the Fédération Cynologique Internationale scores for sensitivity, specificity, positive predictive value, negative predictive value and accuracy. RESULTS: The PennHIP method achieved the best results in specificity (93 per cent), positive predictive value (91 per cent) and accuracy (88 per cent), and the Ortolani method was the best in sensitivity (92 per cent) and negative predictive value (92 per cent). CLINICAL SIGNIFICANCE: The Fédération Cynologique Internationale grades D and E can be predicted with confidence even before animals are one year old.
