It is probably a little unrealistic to be abel to diagnose a poisoning case on initial examination. Bear in mind malicious poisonings in particular are extremely rare but frequently suspected by owners! Symptomatic therapy is usually the way forward, as so few poisons have a specific antidote (rat bait poisoning and adder bites being a noticeable exception). A general approach to a suspected poisoning case shold include:
