Vets- it is profession for patient and loving animals people. I think vets profession dangerous because animals can bite, kick or scratsh them. Vets have to learn about different diseases that animals get and how to treat them. Vets also learn how to theat  animals so that neither the vet nor the animal gets hurt.
