Polar bears at northern Ont. sanctuary undergo health checks under sedation

Cochrane Polar Bear Habitat ready for an update Cochrane Polar Bear Habitat will soon update its onsite information exhibits to reflect new scientific findings about the vulnerable species

Last weekend, the three resident polar bears at a northern Ontario sanctuary located in Cochrane underwent extensive health exams under sedation, including allergy tests an X-rays.

A team of experts from across the province assembled to help the animal care team at the Cochrane Polar Bear Habitat, including the National Wildlife Centre Canada, Bear With Us Centre for Bears, King Animal Hospital, Millson Veterinary Services and the Ministry of Natural Resources and Forestry.

Interestingly, the 1,000-pound polar bears allow their caretakers to perform routine veterinary procedures -- such as administering annual vaccinations, ultrasounds and drawing blood -- without any sedation.

"While our bears are highly trained to voluntarily partake in many behaviours that allow us to care for them without the need for sedation, there were some procedures that require them to be asleep," Cochrane Polar Bear Habitat said in a news release.

"We are thrilled to report that each bears' procedure was conducted without complications and they are well on the way to recovery."

THE BEARS

The trio of bears at the habitat are all male and includes 10-year-old Henry from Sea World in Australia, and father and son 20-year-old Inukshuk and 13-year-old Ganuk.

Inukshuk was orphaned in the wild of the Far North and spent nearly nine years at Toronto Zoo before moving to the habitat.

His son, Ganuk, is the longest habitat resident and largest bear. He was born at a Quebec zoo with his twin sister.

POLAR BEAR ALLERGY TEST

Ganuk was experiencing symptoms that were suspected to be seasonal allergies, so Toronto veterinary dermatologist Dr. Stephen Waisglass conducted a scratch test.

Similar to a human test, a series of potential allergens were administered to his skin, which was observed for reactions such as swelling or redness.

"The test results were somewhat inconclusive, but we will continue to investigate using other testing methods," the habitat said.

ARTHRITIS TREATMENT

Inukshuk is considered a senior bear.

"Over the past couple of months, Inukshuk has shown some stiffness in his front right leg when first getting up in the morning, which could be indicative of arthritis," the habitat said.

"He has been receiving a daily dose of glucosamine supplement, similar to Ganuk, since we started to see the stiffness, but we also wanted to see what may be happening in his joints."

X-rays were taken of his front legs and confirmed some changes in the bone.

"We will continue to provide supportive joint treatment and we remain optimistic with the improvement we have seen," the habitat said.

NEW TRACKING DEVICE

While the bears were sedated, they were fitted with new tracking devices called Burr on Fur as part of a conservation project led by Polar Bears International.

The device attaches to the fur between the bear's shoulder blades and is designed to fall off naturally when they shed in the spring.

"Bears in human care centres play a vital role in conservation projects such as this, as we can monitor them on a longitudinal basis that is just not possible in the wild," the habitat said.

"Not only can we closely observe the equipment to judge its efficacy over time, but we can assess a bears' reaction to ensure that it does not affect their day-to-day activities and behaviour."
