When an owner tells me their pet is sick, I assume it is sick. That may not seem revolutionary, but my point is that just because we don’t think the pet looks or acts sick, and because the patient history the pet owner provides doesn’t set off any particular warning signs, it doesn’t mean that patient hasn’t got something going on. And who would know better that a patient isn’t its normal self than its owner? After all, they’re living with that pet, and they know all their personality traits and habits. So when the owner says, “Max just isn’t himself,” I take their word for it—until I can prove otherwise. And I do that with diagnostics.
