The aim of present study was to determine the dimensions of canine cadaver patella and to evaluate its relationship with the animal body mass. The data from the Veterinary Hospital of the Universidade Federal de Minas Gerais (UFMG) was initially used to propose the division of the groups by body mass, from June 2012 to January 2017, focusing on the body mass of dogs with patellar luxation (PL). From this survey, five body mass groups were formed: G1: 1 to 4.99 kg; G2: 5 to 9.99 kg; G3: 10 to 19.99 kg; G4: 20 to 29.99 kg and G5: 30 to 50 kg. For the patellar measurements, 70 cadavers of adult dogs were used, regardless of race or gender, with body mass between 1 and 50 kg, without clinical evidence of affection in the femorotíbiopatellar joint. The patella and femoral condyle were used with focus on the groove and trochlear ridges of the right and left pelvic limbs. External and internal length, external width in the middle third, internal width in the proximal, middle and distal thirds and thickness in the proximal, middle and distal thirds were performed with an analogic pachymeter. Measurements were also made in the trochlear groove: medial and lateral depth in the proximal, middle and distal thirds and width in the proximal, middle and distal thirds. The data for analysis of the UFMG Veterinary Hospital database were presented in percentage values. Data for patellar measurements were presented as mean ± standard error of the mean. The differences between the groups were analyzed using ANOVA One Way followed by Tukey post hoc. The Pearson correlation was used to assess the relationship between patellar measurements and body mass. For the PL case study, 656 animals with LP diagnosis were considered; of these, 50.05% had 5 kg or less; 35.34% had between 5 and 9.99 kg; 9.56% had between 10 to 19.99 kg; 2.08% had between 20 to 29.99% and 2.97% had between 30 to 50 kg. In general, the patellar measurements showed a strong relation with body mass. Measurements of the trochlear exhibit a moderate to strong relation with body mass. Under the conditions of this study it can be concluded that the size of patella varies according to the canine body mass
