Important to always take the dog to the same veterinarian?
In big cities, many veterinary clinics are made up of a group of veterinarians instead of one. There are some logic reasons for this system. Many hours a day cause fatigue, and veterinarians with particular interests can work as specialists in determined fields. It's also possible to reduce costs to provide a more efficient and satisfactory practice. This means, you don't necessarily need to consult the same veterinarian every time, which is unimportant, cause the records will be there, and can be use by any member of the group. But it is not advisable to change the clinic; the new veterinary won't have the medical history of your dog, or the results of laboratory exams, which will make his work harder; it also can be dangerous for your dog and more expensive for you, as exams will have to be repeated. If you are not satisfied with his treatment, then change to another without any problem. If you go from one city to another, the new veterinary will need all the information about the dog.
