Yes I've had a similar reply. Got this from Pug welfare though:
Hello Jill, thank you for your email. I know it is really disgusting that there are ads like this but we are in a sticky situation. These people are not breaking the law, though some of us have different ideas about it and they are definitely not taking a moral approach to rehoming their dogs. We very much have our hands tied as we can't buy each pug who appears on these sites and it feels as though we are sitting back and doing nothing. The most effective thing to do,I think , is to do what you have done and contact the sites directly and protest about them placing the ads online. Hopefully they will get the message that the public do not want to see ads like this and they might do something about it. We can only hope that she gets someone who will give her a lovely home and lots of love.
Thank you so much for bringing this to my attention.
Best wishes Margaret Trossell (Rehoming Secretary)
