No argument here, if anything your words are too polite OP. I hope that the c* rots in hell.
It's something I say a lot on here but rather that than hear of another tragic story - NEVER EVER leave your dog unattended, not even in your garden, which is where a great deal of thefts occur. Dog theft is rapidly increasing and as someone involved in many areas of rescue I get to hear of it daily.
It's not just young dogs or pedigrees which are stolen - theives don't care, they will steal your dog not just to sell but for breeding, fighting, bait for fighting dogs and to suddenly decide they have "found" a dog when a distraught owner advertises a reward.
The DogLost website is full of such dogs.
It's worth adding here that should anyone lose a dog, that website has a fantastic success rate and it's volunteers, readers and members are incredibly supportive and helpful. I'd recommend them as the first people to go for in order to obtain advice.
