Had My dog "Zoe" for 10 years and got her when she was 2

She died of old age this morning

I really need suggestions but yeah i dont know what to get.. i was thinking something strong that likes to play and live my lifestyle going for long runs and stuff
Need a strong dog to live up to my standards just like my lab did
I was thinking German shepard pup or something like that
Dont need a pitbull :/
Thanks
