A fifth dog at the property was also removed.
Jade was reported to have been visiting the home of friend, who had left her alone with the dogs to go out.
Supt Mark Kenny said: "This is an extremely distressing incident for all concerned, including the community, and we will work hard to establish the full circumstances that led to this tragedy.
"There will be a significant police presence in the area. We will be there to carry out an investigation and address any concerns residents may have.
"It would be too early for us to speculate about what has happened, and further information will be released when it becomes available."
