Please, Please as you were advised in your last question get in touch with Sammy rescue!
DO NOT try and rehome him yourself, especially to someone who you are chasing round their car because they have a sammy sticker in the window!

You have no idea what these people will do with your dog once you hand him over to them.
Sammy rescue know all about the breed and will rehome him with someone who really wants a Sammy, not someone who has not even wanted a dog.
I cannot believe you will hand your dog over to someone who just has a sticker of a sammy in their car window !!! Do you really care for your dog at all? What are you going to do if you see them in the street a few weeks later kicking hell out of the dog? Or like in the above question they put him to sleep within ten hours of getting him? Once you have handed him over you have no rights.
