In a dog this young that you describe as chewing and tearing apart everything I would be most worried about a gastric foreign body that is intermittently causing a blockage. Pieces of toys or trash that are swallowed can get stuck in the pylorus - that's the part of the stomach that leads to the small intestine - and this causes vomiting. The vomiting will often temporarily dislodge the object, allowing things to return to normal for a while, only to block the outflow again. I'd urge you to get Max x-rayed at your vet. A barium series may be required to completely rule out a partial obstruction.
