A raccoon dog who was hiding among nettles and dead branches was watching me as I approached and so I took a photo.
Raccoon dogs are wild animals, one of the earliest forms of dog, and related to foxes and wolves (although no relation to actual raccoons, despite visual similarities) – they often go into a sort of torpor in winter, are mainly nocturnal and are certainly not happy in market cages or houses.
So people who keep them as pets tend to get sick of them.
This can lead to raccoon dogs being released into the countryside, where they multiply rapidly, with disastrous consequences for local wildlife.
Why does your dog wag its tail? by Dr Karl Kruszelnicki

THE DOG HAS been man’s best friend for thousands of years – so you’d think we’d know how to read its emotions.
When the tail is stiff, the ears are tucked in and the body is held tight, most of us recognise it as a warning sign to keep away.
Conversely, if the dog’s tail is wagging and the ears are pricked up and the body is wriggling like a can of worms, then it’s probably safe to pat the dog.
But what about those occasional cases when the dog bites, even though the tail is wagging?
Luckily, recent research has given us a subtle clue to read in the give-away wagging of the dog’s tail.
It happens because the nervous system of an animal is not perfectly symmetrical. Both the nerve pathways that run into the brain, and the brain itself, are wired up in a non-symmetrical way. For example, most male dogs have a strong tendency to be left-pawed, while the females have a weaker tendency to be right-pawed.
The tail is a mid-line structure, pulled by muscles on each side of the body, which are in turn controlled by the left brain and the right brain. Sometimes the different sides cooperate, and sometimes they compete – this means that you should easily be able to see any behaviour that tends to one side or the other.
In a study, when a dog saw its owner, the tail wagged on both sides of the centre-line, but far more to the dog’s right than to their left.
When they saw a random human, the effect was not as pronounced, but still more to their right than to their left.
However, when they saw a large, dominant, unfamiliar dog, the tail wagged far more to their left than to their right.
If the tail wags to the dog’s right, then it’s alright to pat, scratch or play catch with the dog. But if the tail wags to the dog’s left, well, it’s best left to itself.
