Hanna just came into heat yesterday.. she is displaying all the classic symptoms... Not bad so far.. guess Im lucky.. We plan to breed her once she is a year old.. she is 9 months.. My vet told me that You can stop the heat by manually ( using a thermometer) stimulating the vagina.( no more than a 1/2 inch in.) which should cause an egg to drop and thus end the cycle for a while.. He did say that alot of females after being bred are and can be quite aggressive and will attack the male..or you... lol .. Has anyone ever tried this and was it successful at stopping the cycle.? Just curious.
