Thank you all SO much for your lovely messages.
Lela still has diarrhoea so they are keeping her in hospital. But, she is much brighter and has chewed through her drip line - little monkey! The vet thinks she may have a bacterial infection, but we won't be sure until test results come back later in the week. I can go and see her later and bring her home if her poo is back to normal. But I have a feeling she will be there another night.
I'm told the vet nurses have fallen in love with her, so hopefully she is getting lots of cuddles. We really really miss her. First thing my daughter said this morning when she woke up was 'dog'.
I have a (very rare!) day on my own today. Was really looking forward to some one on one time with my delightful little pup. Nevermind, chores instead!
Thanks again to everyone for your support and advice. Pets and children - what a worry they are! Will keep you updated.
