On my way to the shops today I passed maybe a dozen posters on telegraph poles with a photo of 2 dogs on. Thinking it was a lost/stolen ad I stopped for a nose and someone was advertising 2 adult DDB's for rehome due to personal circumstances changing which seemed genuine enough. I dont know what other options the owner has tried but would hope that any enquirers are very carefully vetted.

Cannot understand why the breeder is not taking them back, perhaps they have not been asked but that IMO is the first step to take.

I know its not your job but maybe give DDB rescue a call and pass on the details which are on the flyer.
Lets hope they care more about a new decent home than making money from them..
