Cabergoline is a potent dopamine D2-receptor agonist, acting on on pituitary lactotroph (prolactin) cells.

It is used for pregnancy termination[1], estrus induction in anestrus bitches[2][3] or for treatment of pseudopregnancy.

Side-effects include milk loss post-partum[4].

Recommended dose for estrus induction is 10 - 20 IU/kg/day intramuscularly for 5 consecutive days, followed by an additional single injection of 25 IU/kg of human chorionic gonadotrophin on the fifth day.
