The article deals with the results of clinical, X-ray and sonographic examination of 127 bitches of different breeds aged from 5 to 16 years, which over the years of 2006‑2015 were coming into the clinic of small animals of LNUVMB named after S.Z. Gzhytskyj with neoplasia of mammary gland. According to the initial examination of animals the clinical signs typical for mammary gland tumors were found in 102 (80.3%) dogs. According to the criteria of international clinical TNM classification in 44 (43.14%) bitches was detected the first stage of tumor process (T1аN0M0, T1аN1аM0), in 25 (24.51 %) – in II (T1bN1aM0, T1bN1bM0, T1b, с N1аM0, T1b,с N1bM0, T2аN0M0, T2bN0M0, T2bN1аM0, Т2b,с N1аM0), in 29 (28.43 %) – ІІІ (T1b,с N2bM0, Т2b,сN1bM0, Т3аN1аM0, Т3bN1bM0, T3b,с N1аM0, T3b,с N1bM0) and in 4 (3.92 %) – ІV (T3b,с N1bM1, T3b,с N2bM1) the stage of tumors. In 25 (19.7 %) from 127 dogs, signs of neoplasia were expressed unclearly. Roentgen graphically in 58 (45.7%) of dogs with the II, III, and IV stage of tumors it was found out the local structural changes, indicating the location, size and shape of neoplasia and their relationship to the surrounding tissues; distant metastases in the lungs and liver were detected in 4 animals. According to 69 animals research the obtained results were less informative because of not clear or doubtful for visualization of X-ray structural changes typical for neoplasia. In 95.27% of studied bitches by ultrasound examination MR it was carried out differential diagnosis of fibrocystic mastitis, benign and malignant neoplasms. Summarizing the results of clinical, X-ray and sonographic investigations you can see that integrated mutually complementary interpretation of obtained data is weighty argument for the identification of intractable lesions, diagnosis and monitoring of mammary gland tumors in bitches during preoperative examination.
