I know how it must be for you - my dougal was like that when he got into some chocolate coated coffee beans - I left the room for like 2 mins and they were gone!
He went whizz, whizz, whizz round the house - and he had this look on his face "Momma, I don't wanna do this but I can't stop!
", then he'd puke and go whizz whizz whizz again. Poor little fella! (In my own defence I was still a doggy novice at this stage - I do NOT leave stuff on coffee tables anymore!)
I hope Chloe will get better soon - be sure to give her lots of loves when she comes off her high!
