Another dog has died after jumping over a waist-high ledge at BC Place Stadium and falling up to eight metres to the concrete below.

Yaletown Pet Hospital said Friday that the dog, a six-year-old German shepherd, died Thursday despite attempts to perform CPR on the animal.

It is the third dog known to have died after jumping over the ledge — located near Gate B and Terry Fox Plaza — since the spring of 2013. A fourth dog was seriously injured in May after jumping over the ledge, described by hospital staff as particularly dangerous for the animals.

BC Place said Friday that new measures will be taken to protect the dogs.

“They (BC Place) really haven’t done much of anything other than put signs up as far as an effective response goes, so it would be nice if there was a higher barrier,” said hospital owner Dr. Rob Spooner of the dog’s death. “It’s a good 20-to-25-foot fall onto concrete.”

The circumstances surrounding the four falls are similar — in each case, young, large, healthy and active off-leash dogs walked or ran toward the ledge, then climbed or jumped over it, unaware of the drop to Expo Boulevard on the other side.

Spooner said although there are signs around the wall warning people, dogs can’t read them.

“It’s not an-off leash area, so if people were obeying the rules — I don’t mean to sound harsh or critical — if the dogs were on-leash, this wouldn’t be an issue. They’ve put signs up on the wall, but we’d support some sort of higher barrier. It’s a pretty unassuming looking wall.”

He said a member of his staff called BC Place about the latest death to let them know that something more needs to be done to prevent such deaths in the future.

BC Place spokeswoman Jinny Wu said Friday that new measures will now be taken, possibly in the form of more fences and barriers, although no timeline was given.

“We are truly saddened by this recent occurrence,” said Wu in a statement. “Please be assured that the safety and security of guests and the public are our No. 1 priority. After the previous incident, we immediately added additional signage and notices to remind all pet owners that the plaza area is an on-leash area for the safety of their pets.

“Although there are many signs installed on the plaza to remind owners to keep their dogs on leash at all times, BC Place will be taking additional measures to discourage further occurrences. This may include additional barriers, fences or other options.

“We hope that by raising awareness among the community of pet owners, we can help to prevent these most unfortunate incidents from happening in the future.”
