By putting myself into the animals shoes I mean I take into account the animals nature, personality, behavior, condition etc and imagine that if I was them, what would I think would be the best course of action.
Just as an example a horse with this sort of issue but you know them, so you know the horse is anxious and hates being in a stable or hates travelling then they would maybe choose the less treatment the better option. Or the horse is miserable, painful, weak, given up then perhaps they would choose pts. On the other hand they are good natured, curious, otherwise bright then maybe they would pick the surgery. It's all only what ifs and maybes, might not make much sense, but I like using it at work to help make the best environment possible and treatment plans for patients.
