Maybe mixing cooked meat or another type of people food we could give him? Any advice would be so greatly appreciated.

Teddy, my aunt's dog, has been throwing up the past few days. I told her that fasting him for about 24 hours might help. He's 14 years old, so is he too old to let him go without food?
First you have a dog that has been vomiting for days, and now even though it is eating again, it continues to lose weight. Most likely the dog seems more tired, maybe starting to show signs of weakness. All signs of muscle wasting or a condition called cachexia.

Common causes of the condition include malabsorption, metabolic disease, and undiagnosed cancer. Increasing the protein and fat by feeding a performance or puppy formula won't hurt, but it's really questionable how much it will help. The dog needs to go to the Vet. If the underlying cause is cancer, then you treat the cancer, and the cachexia will for the most part resolve itself. The longer you wait, the less options and remaining time the dog will have.
