Breeding for vigor
This is taken from Ernest H. Hart's The German Shepherd Dog (pg. 92):
"Four important characteristics must be incorporated in your breeding lines if you wish to gain the greatest good from their potential:
1. Vigor: Loss of hardiness or vigor with its allied ills such as lower resistance to diseases, appetite loss, finicky eating habits, etc. must be
diligently guarded against."
I found this very interesting, since I too have a "finicky eater" and I assumed that I had created this little fussy monster. Either that, or he just doesn't like his food, or it didn't agree with him...I have a few excuses, lol! But what do you think? I always thought "vigor" meant healthy, with good stamina. I didn't think it related to the notorious fussy eater that the GSD can sometimes be.
