@elbrant Everywhere you go these days, people warn you of dog-napping. No-one seems to have heard of an actual case, just 'heard tell it is running rife.'
Mostly I believe, from the newspapers, that it is from gardens and homes that the thieving goes on, more than out on walks. Some people I have met have been asked if their dog is a puppy - they say, no, he/she is rising 16. The questionner then loses interest.
A couple of people have become nervous (in the London area) when someone comes up quietly behind them and then sheers off when they stop and turn around. But I think we are all nervous on those occasions. May be quite innocent.
Some people where I walk have loud clusters of small bells on their dogs' collars so they can be heard if not seen. I am seriously thinking of something along those lines. Kito doesn't roam as far away as Mku does. And although I don't think he would allow himself to be caught, you never know. Kito will do anything for treats.
This house has a large garden and I tend to make sure I know where the boys are at all times if I am not out with them. If I am working in the garden, they are usually sunbathing close by. But at night when they go out, I go with them, with a flash-light.
It is scary.
