This is not a joke. See my profile, I ask serious questions. But to put it frankly, I've got a dog that farts too much, and I'm wondering why.

We got this dog about a year ago, and she has always done this. It makes it rough to be in the same room with her. No matter what we feed her, she still does it. About once very 5 minutes. And they are quite audible, and yes, the stink.

I've tried changing dog foods. That didn't help. One brand of dog food seems to help a little bit, but it's the brand that she doesn't like. (a cheap brand) So she will only nibble at it.

It's simply horrendous, in fact, I'm smelling it right now... any suggetions...

The only answer would be to keep trying to find a food that works, It's very much trial and error as foods can have different reactions in different dogs such as the coloring in many foods will effect some dogs and not others.
Some additives you could try that have proven effective are peppermint, fennel, probiotics (yoghurt) and rice.
