People always say "don't worry minis drop late, it's normal, just wait", well, it's not normal, it's a man created issue, they should be down at birth, ok so perhaps they "disappear" for awhile as some are good at holding them up high, but they should be through the canal at birth or shortly after.
So, I managed to cop a feel on Spotty the other day, two little jewels, right where they belong, Spotty is nearly a year old.
His two brothers (one full, one half) were also down at birth, and could have been gelded as yearlings, but circumstance delayed it til they were two year old.
