What is the motivation for breeding and what makes it acceptable? What is improving the breed?
US probably!! ....supply & demand - that's why were all her on COL now because we all love cockers & we all 'chose' to have one (whether from pup/bred or rescued) & the same goes for every other breed out there. Us humans choose a dog we like the look of & that 'fits in' with the life we lead.
Where that dog comes from is up to us.
You don't need 'permission' to breed from your girl & if you've done all the homework you can (& more) & have the support of an experienced breeder ( they are invaluable
) then you have every right to do it, if that is your choice...... but the advice you get from fellow Colers, with an encyclopedic knowledge of 'all things cocker' is good advice & only given because they know & they care.
(if I could just mention little Tinker once again
....bless her The condition she was born with 'usually' affects all pups born in a litter. We were lucky (if you can call it that?) only two had it & normally the litter is PTS
..thankfully we didn't have to make that decision but I don't know if I could of & we'd of been left with 9 blind pups
In all the homework/research/talking to breeders did we ever hear of this condition & the specialist (very well respected & qualified ophthalmologist down here in the south) said it was 'one of those things'. Unfortunately there are many more 'one of those things' out there & i just want to pass on my experience to you so you can be informed & prepared as i wasn't )
