Q. & A. with Casey
Why did you start breeding?
When I was a kid my mom bred 2 litters of Goldens. When I got my first Border Collie I dreamt of breeding and helping to improve the breed. My first bitch only had one litter and it's been 14 years since they were born, but it's still always been a goal to produce sound, sane puppies that would excel at anything.What makes your program special?
I put a lot of effort into my breeding choices. I do as many health checks as possible. I research pedigrees. I am a trainer by profession and love making sure that my puppies get the appropriate first experiences to help them become well-rounded adults that will fit nicely into their future homes.Where do your breeding dogs live?
They live in my home.
