Thanks for your response.
Lola continues to sleep..
She popped out to the garden for a sniff around but nothing else. I saw her pooing/trying to this morning but I can't seem to find it to have a look at (!)
I'm unsure of her weight although she is very lean and usually a fit and strong dog because she is very active.
Unless she ate something out on our morning walk yesterday, (which is unlike her) she hasn't had the opportunity for anything else. I don't think she even went in the garden yesterday.
She ate her usual food and hasn't chewed anything at home etc.
