Objective The aim of this study was to investigate the prevalence ofcranial cruciate ligament rupture (CCLR) and patellar luxation (PL) andthe associated risk factors in dogs.Methods 13,072 clinical records of dogs were reviewed from XX. Data ofage, breed, sex, body weight, PL and CCLR condition were registered.Chi-square and Fisher exact tests were used to compare the prevalenceof CCLR and PL with the variables and then univariable logisticregression was used to evaluate the risk of having CCLR and PL.Multivariable logistic regression was used including all variables to assessthe odds of having PL and CCLR.Results: Of 13,072 patients treated, 72 and 51 had CCLR and PL,respectively. Sex was not a major risk factor for either condition. Adult(OR=8.2) and senior (OR=4.3) patients had increased risk of havingCCLR while for PL age not were a risk factor. Groups 2, 3 and 8 weremore likely to have CCLR (OR=5.5; OR=9.1 and OR=2.6), and group 11had lower risk of having PL (OR=0.08). Maxi (OR=2.4) and giant (OR=6.0) breeds had higher risk of having CCLR, and medium and maxibreeds had higher risk of PL (OR=0.05 and OR=0.3). Multivariate ORtest confirmed that Age (Adult), body size (Giant and maxi), and breedgroup (Group 3) were significantly associated with having CCLR, and agewas associated with having PL.Clinical significance: This is the first epidemiological study of CCLR and PL in dogs from XX. Giant and large adult dogs from the molossoid andterrier breeds were more likely to have CCLR, while mixed and large dogbreeds showed the lowest risk of havin
