The present study was conducted on 320 pet animals including 100 dogs, and 220 cats were ‎admitted to the clinic of the Department of Surgery, Anesthesiology and Radiology, Faculty of ‎Veterinary Medicine, Zagazig University. A thorough oral and dental examination was ‎performed for all animals. Radiographic imaging was conducted on animals that showed ‎clinically progressive periodontitis and bony changes. Animals were classified into five scores ‎according to their clinical dental examination and pocket depth. Animals with a score of 0, had ‎healthy gingival tissue with normal pocket depth, a score (1) of those managed by dental ‎scaling, and scores (2 and 3) of those treated by dental scaling and then non-surgical ‎debridement. Open flap surgery was performed for more advanced cases; scores (4 and 5). ‎Data were statistically analyzed using Chi-square and cramers v tests to investigate the ‎relationship between age, diet, and sex to periodontal affection. Among the total number of ‎admitted animals (N=320), 40.6 % (130 cases) showed periodontal diseases, 8.8% (28 cases) ‎dogs and 31.9% (102 cases) cats. Affected males (24.4%) were higher than females (16.3%). ‎Among the 130 animals with periodontal diseases, 142 affections were recorded. Age and diet ‎showed high statistical significance (P<0.001). Sex showed to be statistically insignificant, ‎‎(P>0.05). The cramers v test results for age and periodontal disease association showed a value ‎of (0.490) and strong association between age and periodontal diseases
