I would of been a spy and chatted to them- all sweet making out wanted a dog- found out who the gits are got an address then called the rspca- It is illegal !
Chances are these pups may have been stolen. A litter of stolen pups near me were seen for sale from the back of a car near Reading, and the people selling them thankfully got caught but somehow as is the way of these things got off scot free! Then as they were travellers disappeared off into the night.
oh those poor puppies. some people don't deserve to be on this planet! what goes round comes round (so they say) so one day they will get their come uppance.
