Excessive salivation can mostly commonly be due to nausea or can occur immediately after eating something caustic like certain plant material that is very irritating to the mouth. It can also be caused by tooth pain or if they have chewed something that is stuck in the throat/tonsil (this is often accompanied by excessive swallowing or hacking). I'm not sure how long he has not been drinking but it is likely secondary to whatever is causing the drooling. I would check his mouth for an obvious tooth issue or foreign material. If the drooling is continuing i would have him evaluated by a veterinarian. They can do a complete oral exam and also palpate his abdomen to sort out what is causing the salivation. They can do tests to figure out if there is more serious underlying cause (e.g. Pancreatitis causing nausea) and can prescribe medication accordingly. I really hope glen is feeling better soon.

    Excessive salivation in the absence of drinking may be an indication of nausea. It also could be an indication that Glen could have gotten into something toxic. My advise would be to take him to the vet for an exam as soon as you can. They will be able to get the nausea under control, and assess his physiologic function. If there is any chance he could have been exposed to a toxin, think about what that might have been, as it can help the veterinarian come to the most appropriate treatment plan. Hope this helps! Let me know if there is anything else I can do for you and Glen.
