After looking for ages I finally found a breeder I think might be good ( i live in New Zealand so its quite restricted)
But i really don't know much about finding a good breeder, I would really appreciate it if someone could give me their opinion on this breeder or recommend others.
The reason I liked they was that they said this;
"It is of major concern to me that many breeders are not taking the long term welfare of the breed into consideration and are instead concentrating on the immediate gratification of show wins and there by putting at risk the continued successful development of all 4 colours of the breed."
but what do I know
