Use of cabergoline for oestrus induction in multiparous anoestrous Beagle bitches

The purpose of this study was to examine the efficacy of daily cabergoline administration on oestrus induction in bitches.

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.

Cabergoline is effective for oestrus induction in mid-anoestrus bitches.
