Nowadays, with the development of new technologies, improved and progressed methods have been taken to diagnose, treat and prevent cancers. Pathologic study and some molecular methods have been helpful in diagnosing and predicting cancer but these methods are not enough in many cases. Omics technology investigates many parts of cells such as genes, proteins, transcripts, and metabolites simultaneously. This procedure provides a more real and general feature of cellular processes, especially in cancer cells.    In human, Omics technology is widely used to diagnose and treat various cancers and predict  prognosis of tumors and survival of patients. In parallel to the studies of cancers in human, similar investigations were conducted in the canine cancers. Regarding the importance of Omics method in oncology, we described various Omics techniques including genomics, transcriptomics, and proteoimcs. In addition, corresponding studies carried out in different canine cancers were summarized in the next step.

Clinical and pathological findings were described in stillborn kids affected with congenital goiter in a goat flock of Beetle breed in Garmsar Iran.The observations involved seven stillborn kids with goiter, including one case with triplet fetuses and two cases with twine fetuses. The thyroid glands were clearly visible, enlarged, and palpable in all the dead kids. The fetuses had a large swelling in the cranio-ventral neck region. Upon cutting skin in each fetus, the swelling revealed the extremely enlarged thyroid gland with two almost symmetrical lobes with both lobes approximately 15 × 8 × 5 cm in size.Histopathological hyperplastic goiter was observed in four kids and colloid goiter was diagnosed in three.Twins or triplets were observed to be predisposed to congenital goitre. All the stillborn kids were twins or triplets. On the other hand, single-born kids survived and showed a normal growth rate.
