– Well then you’re almost a veterinarian... – The girl concludes thoughtfully.

What is wrong?
Usually, 90% of adequate adults do not run away from the doctor, do not resist (including bites), more or less accurately describe their condition, where it hurts and so on.

So the pediatrician is practically a veterinarian and he has to guess about the symptoms of the disease without interviewing the patient - exactly like the veterinarian.
And a child can not always be believed - it can either simulate not going to school or, on the contrary, hide not getting an injection.

A 100% certificate from the veterinarian.

I highly recommend reading about the work of veterinarians "in the field":
