Probably so ....I've just never know any . They were all " family " whether producing or not .
See my dogs are family as well.... and I have my original terriers here to this day. However it just rubs me wrong that you seem to be insinuating that breeders who rehome retirees are not giving their dogs that family life.... If a breeder in breeds such as JRTs ( Live easily 14 years and up... ) does not retire any, and has 2 dogs they breed even every couple of years ( and most have at least 3 or 4 ), they keep one pup to promote... in just 5 years they'd have 7 dogs, and may be unable to continue working and trialing their breed without the option of finding great retirement homes for them.
I know a great breeder whom is an avid hunter, I was at his home once when one of his gang had a birthday and they had "meatloaf" cake for him... I have had meals with them often with a terrier on his lap waiting patiently to be offered a treat. His dogs live in his home and are a part of their family... He has placed retirees though, and will have to do so in order to carry on. He kept his foundation terriers until the end, but has found great homes for others...
I have heard it described like a child growing and leaving home, they keep in touch but are in a different home... The breeders that I know who have to d this, don't do it lightly... and find homes they really trust and believe in, where they can keep up with their dog.
I do know a great many BYB's however, who have a few dogs they love, and because they don't do anything with them besides love them, they have their dogs until the end... They breed them until they cannot breed anymore and then just let them live out their lives at their home, happy I am sure but I'd rather the pup from the breeder with their breeds best interests at heart, rather than the one from the BYB who loves his/her dogs but cares little about the breed...
Just my opinion though.....
