Well, I screwed up again it seems. I banded a 500 lb calf with what the vet said was "too small" of a band. I used the old green cheerio looking band but the calves are bigger than I normally band at. Now the problem is, his sack is black and appears swollen more than normal. It appears black and irritated looking on top of the band as well. The "steer" is moving ok and acts fine but the sack area looks terrible. With this said, I failed to give a tetanus shot and I put the band on about 10 days ago. What should I do now? The vet said to give him more time with the band but I didn't ask about the tetanus shot. Should I give him a tetanus toxoid shot now? Antibiotics? Please help me cuz this is a mistake I won't make again.
