Is it easy to be a vet?

No it is actually somewhat difficult to become a fully certified small animal vet. You almost certainly have to get a four year undergraduate degree in science/animal biology which can be difficult but very doable. But, then you again have to apply for a graduate degree which often takes another four years (2 years studying and 2 years of unpaid work at a local vet office). Yet, once you do complete all this schooling you get paid a ton of money and get to deal with animals all your life. So although it is not easy, it is a very rewarding career. I would look at tufts in MA as that is a very well renowned vet school.
