I need 2 know when a Yorkie would die an i need 2 know when a German shepard would die.
It depends – if you treat them well, they might just gain a few extra years. German Sheperds live about 10-12 years – avarage dog life-span. But they have a bigger-than-avarage tendency to have hip dysplasia. My used-to-be dog, King the German-Sheperd, lived a short and ill life – seven years. However, it did had to do with the time he spend without walking or going out, he shrunk a bit and got ill.
Yorkies are smaller dogs, so their avarage life span must be bigger, like about 14. However, don't only trust the facts, because a premature\later death can be provoced in both breeds.
