My 5yo collie has eaten what I'm guessing is about 100g of sugar. It is entirely my fault and I'm very aware of how stupid I was to leave it within his reach.
I've Googled it and nobody says much about sugar, more about the dangers of sweeteners.
So, it must've been late last night. He's drunk lots more than normal through the night and has vomited twice this morning. He seems ok in himself just very shamefaced as he knows it's forbidden to get into shopping bags. I didn't realise I'd left the sugar in there, just tins for my mum 
Can anyone help reassure me? My plan is just to observe today and take him to the vet if he doesn't get better so I suppose I'm asking if there's any need to rush him there this morning.
Thank you.
