GALLATIN, Tenn. -- The state veterinary board has reversed its decision and lifted the suspension of a Sumner County vet accused of using controversial euthanasia techniques.

The Channel 4 I-team first showed video of how Dr. William Baber was giving “heart shots" to dogs and cats without anesthesia, a practice that is banned.

Baber and his attorney asked the board to let him treat animals in his private practice until a full hearing next month, saying he had been fired from the Sumner County animal clinic anyway.

"Because he was relieved of his duties, action by the board was not required," said Baber's attorney John Pellegrin.

Last week the board saw for the first time hidden camera video of Baber injecting the chests of dogs and cats without first sedating them.

Board members met by teleconference on Wednesday and some had second thoughts about the suspension and said it was too harsh.

"No one sedates animals before they're euthanized," said vet board member Joseph Kendrick.

The board voted to let Baber practice as long as he doesn't euthanize any animals, a vote that the state's attorney did not agree with.

"He obviously violated standards," said board lawyer Alison Cleaves.

Baber, who had never talked on camera before, broke his silence on Wednesday and said he was relieved by the decision.

He said he wouldn’t say much about the controversial killings now that the Sumner County district attorney told him he will be charged with a crime.

"The DA told me he will be charged with a misdemeanor," said Pellegrin.

One board member said Baber should have known better than to euthanize dogs and cats without sedating them. The member said Baber was playing Russian roulette with his license.
