Wow... several serious conditions, and now an enlarged gland, too... Seems likely at some of these issues are related.
first of all, you said initially it seemed his lymph nodeS were enlarged (more than one?... or just one?). Salivary gland mucoceles or infected glands are often confused for an isolated lymph node enlargement... but more than one would very unusual.
2.- your puppy has Diabetes insipidus? Pretty rare condition. How are you treating him for that?
3. are you treating his Cushings? Is he better? What were his symptoms initially... difficult to manage sometimes the polydipsia (excessive drinking) of BOTH Cushings as well as Diabetes Insipidus.
4. Enlarged Salivary glands on their own are rarely a serious problem though they can be a result of infection (common to have infections in Cushingoid dogs). Rarely is surgery needed unless it is massively swollen or full of excessive saliva (aka a mucocele). Otherwise, most often, just medication will shrink it up. If he is having trouble eating, an infection would be high on a list of possible causes. Might require antibiotics and hot packing, though unsure where the exact infection is or what would be its cause (a foreign body that was ingested could certainly be the cause). And ultrasound or even an MRI of his neck would be helpful (but costly of course).
