The last sentence on page 230 “Also, this is the first case in veterinary literature in which karyotypic analysis was performed.” has been corrected as follows: “Also, this is the second case in the veterinary literature in which karyotypic analysis was performed and as in the previous case report (Zucker et al. 1993), there was no chromosomal abnormality determined.” The sentence has been corrected upon a notice of Dr. Zucker sent to the corresponding author on December 21, 2018. The authors apologize herewith to Dr. Zucker for their unfortunate oversight.
