My mom's 5 yr old, female English Mastiff has very, very stinky gas. And she gasses pretty often, which can (and does) clear a room!

Is there anything we can give her to maybe get the stench down? A certain vitamin or something?

If there is anything, please let me know... it will be VERY appreciated!

I had a very simliar problem with our Lab. His gas got so bad, i was embarrassed to have company. We changed his food gradually and it made all the difference. We use a lamb and rice Nutro Max.
