Guzoo has been the focus of animal abuse concerns since it opened in 1990. In March 2011 someone posted pictures of a goat with its face covered in blood on Facebook.

The Alberta government ordered Guzoo shut down in 2011 over concerns about animal care, but later reversed its decision.

The province granted the zoo a new one-year operating licence in April.

Officials with Alberta Environment, which regulates zoos, could not immediately be reached for comment.

Last fall a government spokeswoman said an inspection of the zoo’s operations in July 2012 showed no problems with the health or condition of the animals.

Gustafson declined to comment on the content of the video or the animal welfare activists.

“They have been here about four times now. They have escalated. When this started out it was just a verbal thing a couple of years ago,” he said.

“Now they start damaging property and breaking and entering. Who knows what will be next?”
