There's nothing worse than the moment of panic that sets in when your pet starts acting strangely, has an accident or generally just becomes very unwell quite rapidly. We've all been there and it's absolutely horrible. Most of the time, the problem is resolved by a quick phone call to your local vets in order to get an appointment. Sometimes, though, these things happen in the middle of the night, on a bank holiday or some other inopportune moment. That's when the real panic sets in.
