Use of cabergoline for oestrus induction in multiparous anoestrous Beagle bitches.

Abstract

OBJECTIVE: The purpose of this study was to examine the efficacy of daily cabergoline administration on oestrus induction in bitches. METHODS AND RESULTS: Of 20 multiparous Beagle bitches, 15 were not mated with sires in their last oestrus and 5 bitches that had been mated whelped. All bitches were in early or mid-anoestrus and received 5 μg/kg/day cabergoline PO. Oestrus was induced in the mid-anoestrus bitches at a higher rate than in the early anoestrus bitches. Comparing the different histories of previous pregnancy among the mid-anoestrus bitches, the rate of oestrus induction in the non-pregnant bitches was higher than in the bitches that whelped. CONCLUSION: Cabergoline is effective for oestrus induction in mid-anoestrus bitches.
