I went to visit Caleb yesterday and discovered he has a 2.5 cm long twig (about 4mm in diameter) stuck just above his shoulder in his neck under his skin. I felt a bump and when I looked to see what it was I saw the end of a twig sticking out. My barn owner said this happens every once in a while and they need to be cut out or else he will get an infection without question. He didn't tell me what kind of plant it is but said that they have barbs on them and are very difficult to remove.
The farrier is going to take it out on Thursday, hopefully everything will go well, he's also having his feet and teeth done, he's going to have a fun day Thursday.
Hopefully I can get the name of this plant as it is clearly dangerous.
Has anyone else had something similar to this happen?
