Coupan?

An Australian mystery animal with a long fluffy tail was chased by a witness' dog:

"'It was as big as the dog (big) but skinnier and very muscular and it had very small ears close to its head and a large dark face.
"'It was the reddy gold colour of a setter.
"'It moved like a cat not a fox/dog and I am sure that if it had been a dog Zak would have approached it very differently as he is friendly, submissive and very polite in his dealings with other dogs'" (News source.)
