If you really do it right breeding now could but some serious financial hurt on you. All the genetic testing, DNA, microchips and vet bills the list goes on there. Then with a heavily coated breed like the cocker you really have to have an expert groomer and handler to keep them in a "show coat".
So...working full time to spend thousands a month on showing/breeding or work part time and have time to quilt and spend with family without a grooming brush and clipper in my hand...no contest!
