My dog is vomiting clear liquid - 8 times today

Thank you for your question. Unfortunately, vomiting with that frequency and weight loss are reasons to have your dog seen by a veterinarian as soon as possible. It is possible that your dog has a foreign body, an intestinal obstruction, or an infection or parasite. They need to be seen as soon as possible. I hope that everything goes well and they feel better soon.

He has losses weight, not Eatting, and not as active as usual

Hello, So sorry to hear about your dog. If he is not eating and losing weight there are many things that this could be such as gastroenteritis, metabolic disease, or endocrine issue. It would be best for your vet to look at him. They will want to run bloodwork and take x rays to help figure out what is going on. I hope your dog starts to feel better soon.
