She also had a deep incision on her abdomen.
The monkey was removed and taken to an experienced veterinarian for examination.
The animal had to be euthanized.
On Wednesday, the court found Alberts guilty of animal cruelty, obstruction of justice and illegal possession of an indigenous wild animal.
Wilson said the matter had also been reported to the veterinary council, but it said it would only take action after the case was concluded.
“It has taken nearly eight years for justice to be served for the monkey that was so terribly abused at the hands of a veterinarian who, by their chosen profession, should have had the animal’s best interests at heart.
“The NSPCA will never give up seeking justice, no matter how long the justice system takes. Every animal and each case matters to us,” Wilson said.
Alberts is expected to be sentenced on March 18.
