Hi everyone, I'm new to this site and found it through a serach engine because I need some advice about my staff puppy.
Bonnie and Clyde are 8 week old staff's (brother and sister) and I wormed both of them 3 days ago.
This morning Clyde ate a small amount of his breakfast (he has been fine since we had him which is only for 5 days and has ate and drank normally since then), but since about 10.00 this morning he has been intermittently vomiting and has diarrheoa. He hasnt eaten or drank anything since the vomiting and diarrheoa began. His poo's arent watery but appear to be like clear mucus, (it looks a bit like wallpaper paste) and smells foul. He hasnt moved off his bed all day (only be sick and poo) and is extremely quite (he's the boisterous one out of the 2).
Bonnie is fine, the same she was when we got her. She hasnt been sick nor had diarrheoa.
Has anybody got any suggestions or advice. I am now getting quite worried about Clyde and the kids are getting upset thinking that he is going to die.

His belly is not bloated but I afraid of him getting dehydrated having not drank anything all day. Should i force some water into him?
Could it possibly be from the wroming tablet??,,,this did cross my mind but then again, his sister is not ill like him so i didnt know whether it was or not. Maybe it has affected him differently.
PLEASE HELP.....anything is very, very much appreciated.
Thank you.
P.s they are both at the vets tomorrow for their first jab so hopefully our vet can shed some light on these symptoms and make him better but till then I dont know what to do or what it could be.
