The aim of this study was to evaluate the blood profile and haematological changes in obese adult and senior dogs. An evaluation was made from the blood profile of 59 obese adult and senior dogs. The animals were divided into two groups, group 1 (G1) with 30 obese adult dogs (2 to 8 years) and group 2 (G2) with 29 obese senior dogs (over 8 years old). The mean values of the erythrogram and platelet count parameters of both groups remained within the compared reference ranges except the red cell distribution width (RDW), whose values were lower than the reference ranges in both groups. A comparison of the values of erythrogram and platelet count of the groups indicated that the RDW and MPV (mean platelet volume) of G2 were higher than those of G1. As for the white blood cell count (WBC), only the number of band neutrophils exceeded the physiological limits for the species in both groups, with no significant difference in values between the age groups. The males in G2 showed a significantly higher mean eosinophil count than those in G1 and than the females of both groups. As for the frequency of findings, 90% of the animals in G1 and 68.96% in G2 showed left shift neutrophils (LSN), while 34.48% in G1 and 20% in G2 showed eosinophilia. It was concluded that, irrespective of age, obese animals presented no changes in erythrogram and platelet indices, and that their WBC may exhibit discrete LSN without leukocytosis.
