Hi again,
The people I really could strangle are those who buy a puppy (or kitten, but more noticeable with dogs) for Christmas, and when July/August come, leave it on the road somewhere, sometimes with a note saying 'Please look after me', but more often without anything, and even tied to a tree. (Where passers by rescue the poor animal and take it to a centre)
The owners are punished with a hefty fine if the dog is tattoed/chipped, but unfortunately there are many owners who do not comply with the Law (having your pet tattoed or chipped that is) and escape unpunished.
