Twist in the tail...

The only eyewitness of the sheep attack now says that the black dog he saw (in the middle of the night, from a great distance, through a bush, in the rain…) “had a curly tail”.
The owners of the Poodles have asked me to come up with a list of blackish dogs that might fit this description.
I’ve included dogs that can come in black (or appear to be predominantly black when seen at night) and can have tails that might curl. (I’ve seen very unlikely tails curl when very excited.)
On current form there’s every chance Sussex police will start doing a house-to-house on this case and decide to bring all dogs of these breeds in for questioning.
If so, the Poodles’ long-suffering owners can now recommend a very good lawyer….
The two dogs currently held by the police don't have 'curly tails'. But perhaps the police suspect the dogs were wearing cunning disguises? Perhaps complete dog suits that also prevented them picking up any forensic traces of dead sheep on their very absorbent coats?
Or perhaps the two Poodles, now locked up for over a month without grooming, boosters, flea control or worming, could just be innocent…

Can you add to Sussex’s most wanted – please post in the comments section any additional possible suspects?
