Does anyone else have a Whether that looses ALL of their hair (except the hair on their face, & most on their legs) when shedding in the spring time? I have asked the vet about it & she said that since he does it the same time every year it should be okay. No tests were run. But I don't want him to loose ALL of his hair right now, because even though he has a heat lamp in his shed (it goes off around 8PM) it is still 35degrees at night (45-60 during the day). Anyone know what causes this? He is on a goat mineral supplement and he has a billy goat salt/mineral block.
