The reason that people are concerned about free ad dogs is for all the reasons that the above poster has said. I would advise anyone to ask for a donation and if you don't want to keep the money you could give it to a charity of your choice. I am quite happy to do a home check for you ,it does reduce the risks associated with free ads.
Sadly there are people who do trawl sites looking for free dogs to use as bait, its a fact of life and makes replies like this necessary. Please feel free to message me if you would like me to do a home check.not everyone feels comfortable doing them
