Hi,
Could anyone recommend any good books on Genetics and Breeding please.
Thanks

If you can find them look for books by Dr Malcolm Willis. They were written with GSD's in mind but in my opinion are about the best you could find. You will only find second hand copies now and be prepared to pay big money. I did hear of a copy being brought on Ebay a few months ago by someone on here for £55 but that is unusual. Prices these days are nearer £70/£100 per book.

Best wishes, John
