she is 3 months old

I feel dizzy I am so upset, I don't know what to do with myself. Now I am reading up on liver shunt, and as much as she doesn't seem to have the symptoms now (she was wobbly as a puppy when i first got her but I think it was just kind of like how baby horses are) she has perfect balance now, unless a pile of pine needles is too high and she runs into it. Anyway, I know she has no symptoms of this now, but what if they are just mild and i don't notice them?
Can they detect liver shunt this young in a puppy if i get her tested? Even if it is mild???
ugh i hate this, my poor baby
