"We are very grateful for the community coming forward with so much information, without their statements we wouldn't have be able to link back to the exact dog involved," Ms Stanford said.
"It is a tough process making sure we link all the dots and the different statements together to make sure we are positive we've caught the right dog.
"This is a very emotional time for everyone, including the dog owners of all dogs involved and the witnesses. The owners of the blue heeler have been very co-operative."
