What does DVSE stand for at the end of the vet's name?

This isn't a standard abbreviation for a degree, title, or certification in the United States, so I'm not sure what it would stand for. I would guess it is something along the lines of "Doctor of Veterinary Science", although I can't figure out what the "E" would be for. The abbreviation for Doctor of Veterinary Science is DVSc, which may be what you are asking for.
