Exploring the pasture
I purchased three bucklings this spring from two different farms. I gave them their CDT shots on 6/3. Organizing paperwork and realized only one of them had received the first CDT shot in May, but now it's been 7 1/2 weeks since I gave them the shot. Do I go ahead and give the two who didn't get the booster the second dose or start over again and give them another "first" shot and then a booster 4 weeks later? Thanks for advice.
