[Jacob-list] Penicillin for sheep

[Todd Heins]

I had to take a ewe to the vet to get her leg stitched up.  My vet told 
me to give her 10 ml of Penicillin for 6 days.  I have a bottle of 
Pen-Aqueous that recommends 1 ml per 100 lbs.  I probably wouldn't have 
questioned him about the dosage but 1 ml compared to 10 ml is quite a 
bit of difference.  His response was that the label on the bottles is 
out of date and from the approval many years ago.

Is 10 ml too much to give to a 100 lb Jacob ewe?  I have always heard 
that the first dose should be a double shot as a booster.  At double, 10 
ml is a lot of penicillin for one shot.

Has anyone given that much to a Jacob ewe?  Is my vet out of his mind?  
If he had recommended 3-4 ml, I might not question it.
