is my bp dehydrated? someone help

As for the pedialyte, I don't want to give you a wrong answer so hopefully someone who's done it before can answer.

if i give him pedialite how long should it be before i see improvements?

Pedialyte works pretty damn fast. I'd say you should start to see improvement by the next day but again, maybe wait for someone with more experience to chime in

how long should it take before he is rehydrated? how long should i give him the pedialite?

ignore that last reply my internet is kinda slow and i didnt think it posted the fist time
