Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Acute onset bloating of the abdomen and vomiting or attempted vomiting could indicate a condition known as gastric dilation volvulus (GDV). Hopefully this is not the case, but I would recommend getting your dog to your vet straight away to be checked over to be sure this is not that case.
Let me know how you get on.
