I have a fb pup her breeder has her on royal canin mini so I have kept her on this and her poop is still sloppy with jelly in it she has been wormed so that rules that out I'm wondering if this is normal as iv only ever used royal canin medium junior and adult foods and not had a problem any suggestions I'm at the vets in a weeks time but wondered if anyone can help iv had the pup a week and a half

I fed RC mini junior to my toy breeds for years. 

Sloppy with jelly doesn't have to be worms.  Could be Giardia or Campylobacter.  Take poo samples with you.  But would definitely not want to wait a week with a pup if it is campy to be honest.  A week makes a big difference to a youngster.
