My name is***** and I am sorry to here that Browser is not felling well tonight. Is he having diarrhea to go along with the bad gas? Any vomiting? Any dry heaving? Can you look at his gums- are they medium pink like normal or pale or red? Is his abdomen hard and distended or soft and non-painful?
Based on your history, I would strongly suspect that he has some very severe intestinal upset. The trembling could be related to the intestinal upset as well, but he could also have other metabolic problems.
Do you have a local animal emergency room near you? He may need to go see them this evening, especially if he is having diarrhea or vomiting.
If you do not have an ER near by, you can give him some Pepcid, about 0.5mg per pound. I would guess that you meant to say he weighs 70#, not 7#, so I would give him 40mg of Pepcid and see if that helps.
Best regards, ***** ***** this answer helps you.
Feel free to contact me if you have any more questions.
