following on from @Dbirk comment re the killing of unwanted breeding bitches / stud dogs / unsold puppies,
if anyone thinks / believes that some / most of these puppy farms will take the unwanted dogs along to the vet to be pts,
they are mistaken.
the bad ones will dispose of the dogs in other methods.
which I am not going into here, as that would totally spoil this thread which is all about finding a dog for the OP.
no, I do not work for / have not worked for Many Tears.
no I do not / have not worked for any animal rescue.
yes I have volunteered many years ago for a small animal rescue.
yes I have fostered for Many Tears - years ago
yes I have adopted from Many Tears - 3 times.
and yes I think Many Tears may very well have a suitable collie for the OP,
and yes I think the OP should be eligible to adopt from them - having asked the OP re children / garden / working.
