The first rule of requesting veterinary assistance is to call while there is still time. Animals caught in the early stages of a problem will often respond rather quickly and with simple treatment. Calls early in a health problem and early in the day will save time, dollars, and a good relationship with the vet. The fear of a costly course of treatment often holds many back from calling a vet, but if the call is delayed too long the treatment may be even more costly or the animal lost.
