Is.Ace Safe For.Goats?

[blackie's maiden]

We have an otherwise gentle brèding buck that we just.cannot trim his feet. He charges, tries to gore, very scary. Our horse.farrier.gave us a 1.5 cc shot of Ace to give him. But after hearing that anesthesia are so dangerous for goats I thought I better ask first. He is a really big boy and otherwise very gentle. I don't think Hubby and I together could knock him down and hold him. 

Would the Ace be OK?  And if so, how much since the 1m
.5 was for a horse? Thanks.
