does anyone know of a shot or pill to give to a dog to make them come into heat?

I know it can be done with pigs but, I too, am wondering if there isn't something like that for dogs.

There are several ways but they are not recommended due to the stress on the animal, reproductive tract disease and the variable success rate:

1. The use of exogenous estrogen to prime the hypothalamic-pituitary-ovarian axis so as to either induce a false pro-estrus that is expected to be followed by a normal proestrus or induce a proestrus that will progress in a fertile estrus when supplemented with a subsequent gonadotrophin administration.

2. The administration of one or more exogenous gonadotropic hormone preparation to stimulate an ovarian response that results in proestrus followed by a fertile estrus with either spontaneous ovulation or ovulation induced by additional hormone (hCG or GnRH) administration.

3. The administration of gonadotropin releasing hormone (GnRH) or a GnRH-agonist in a manner that elicits pituitary release of endogenous gonadotrophins LH and FSH sufficient to provoke an ovarian response that produces normal proestrus and subsequent fertile estrus and spontaneous ovulations.

4. The administration of a dopamine agonist that provokes hypothalamic or pituitary hormone responses that lead in time to a premature but otherwise apparently natural proestrus and fertile estrus.
