Yes, I do feel that she may have MG or another respiratory disease that is causing the gaping and swallowing. Testing could give you the answer. I agree with giving water, and occasionally electrolytes and vitamins can be helpful. All of the other fad additives are not necessary, and may be harmful, especially if they won’t drink the water. VetRx has nothing in it to cure a respiratory disease. It is a mix of herbal oils and camphor. Iwould try to get some Tylosin or one of the other antibiotics to treat MG.
