Just want to say what a great discussion, will keep reading with interest...
And personally, my quick thoughts are that whilst I have two amazing springer boys, I would love to see the day when the only springer you see is in a good working home/environment in the country... I don't think they should be 'family pets' with no working activities....
Now, don't get me wrong I know many of us have these dogs in the city and without working them... and as long as they continue to end up in rescues and are in need of a good loving home, then my door's always open to the breed - I like to think that tho I confess to being oblivious to the working and training that some of you do, I do put in a lot of work keeping my boys stimulated and exercised... But because I can recognise that they are working animals, they were bred to be out in fields and hunting and being on the go 12 hours a day, then expecting them to simply fit in with our more domesticated lives in the 21st century without side effects is showing naivity on the part of a lot of humans... and breeders who sell them on as family pets should get some severe slaps on the wrists if not much worse...
Selina your post had me in tears,

it's so sad that you see such created problems in animals and have to make heartbreaking decisions either way...
Sandy, going back to one of your posts early on... I do agree with you that once a dog cannot work anymore then if there's a choice between expecting it to go into a domestic home as a pet or have it PTS, then I too would feel the PTS would be in the better interests of the dog, and thank you for being brave enough to post that... Sometimes I don't say what I really want to on this site, I know it's my opinion and I'm entitled to it, but the fuss a wrong word can create is sometimes enough to get me to keep my mouth shut

But there was a thread many months/years ago asking people on here to sign a petition to save a dog (I think it was a German Shepherd) that was an ex-police dog, it couldn't work any longer due to age, and it's fate looked like it was going to be PTS... The petition on here - and not knocking the good intentions of the poster - was to save it, and to encourage the police to re-home it as a family pet... How can that be the responsible thing to do?! as heartbreaking as it is, sometimes we all need to realise as much as much as we don't want to give up on every sweet dog that looks at us with puppy eyes and a wagging tail, some decisions need to be made from the head and not the heart...
I think of how hard you worked with Honey and such a tragedy that you all endured Sandy, and that was with you a responsible highly experienced dog handler and worker, imagine her fate and how much worse it could have been if she had been found and re-homed in another, perhaps less scrupulous, part of the country, to someone with no idea of the breed or the willingness to learn who just wanted a 'cute springer'...
I guess I shouldn't say too much cos on the whole the rescues do a great job... But i think some of them still don't do everything they should when re-homing this breed of dog... My own personal experience of getting Sonny shocked me and make me understand wholeheartedly how these dogs can end up in the wrong homes even when going through rescue channels...
Sorry, I only meant to post one sentence and now I've ended up waffling!
Very interesting thread!
