Auburn University's College of Veterinary Medicine, the oldest in the South, sits roughly two hours from Birmingham. For a dog whose seizures start somewhere between one and five years old — the usual window for idiopathic epilepsy — that drive is where the expensive part of the diagnosis happens. Ruling out a structural cause typically means advanced imaging and spinal fluid analysis, and that is referral-centre work rather than something a general practice does.
Here is the part worth planning around: that trip happens once, or perhaps twice. Everything after it is local, routine and permanent. A daily anticonvulsant, refilled monthly. Serum drug levels checked periodically while the dose is being titrated, then at longer intervals. Liver values monitored on some protocols. None of it is dramatic and none of it is optional.
Birmingham's low cost of living covers the visits generously and the drugs not at all. That inverts the usual advice about cheap markets: the thing to build a reserve for here is not the emergency, it is the standing order.
