Yep, they are in the back of the owners car, travelling home as I type. They were dumped and handed in to a vets, following all the publicity on news sites, FB, Twitter, Doglost and all of the other sites. No doubt there will be happy reunion pictures soon!
Thank you all so much for your help, I know some HHOers have been helping, I've recognised some user names on other forums. The owner has been overwhelmed by all the support she's received.
For everyone else looking for missing/stolen animals, there has been some great advice on here. Don't give up.
Thank you all again for your support xx
