Do deer lose their antlers every year?
Mule deer, whitetail deer and other ungulates shed their antlers once a year. It can take as little as 24-48 hours for the antlers to actually fall off, but the shedding process takes between two to three weeks and then new antlers will regenerate throughout the summer.
Deer (and other ungulates, like elk) shed their antlers every year, then grow a completely new set. This shedding procedure takes two to three weeks to complete, while the regeneration takes an entire summer to complete — before the cycle starts all over again.
