This post isn't directed at anyone, it is a general "just saying" post..
When we bought our first horses in Canada, they came from an auction, both pregnant. Did I rescue them, no, they were both in great condition, did I outbid the meat man, well yup, sure did.
The first thing I did when I got them home was to call the local vet and organize a routine visit, this made sure he knew me, my horses and most importantly how to find me.
Over the last few years we have built up a great relationship, I consult him by phone often, drop into the surgery to ask questions sometimes, make sure I buy my meds through him, just generally have a good relationship. He knows when to come here, when to suggest I go to him, and when to go for wait and see, that is because we trust each others judgment, he knows I'm not prone to panic and call him if not needed, and that I can accurately relay what is happening here.
Do I always pay on time, nope, we are farmers, come July/August we tend to be living on fumes, all our money is invested in the crop, so a colic scare just can't be covered, does he get paid something every month until it is cleared, hell yes. When we sell grain I tend to bank a little with him as well, future proofing, when you have horses you will have bills, that's for sure.
