How long do beagles stay in heat?

Answer 1

A female beagle's heat cycle can last anywhere from 2 to 4 weeks. A beagle goes into heat twice a year, starting as early as 4 months old, and will continue for as long as she lives.

Answer 2

Beagles typically stay in heat for about 2-3 weeks, but this can vary. The first stage is proestrus where there may be bleeding or discharge, followed by estrus where they are fertile and receptive to mating. Finally, there is diestrus and anestrus, marking the end of the heat cycle.
