My dog farts all the damn time. We throw him out in the garden as soon as we smell mouldy kibble. LOL
There is no clear limit. When he starts clearing the house, it has reached that. He must go outside at that
Yes and my tolerance limit is one. A friend of mine had his dog in the cab of his truck when it farted, he went in the ditch because he couldn't get the window rolled down fast enough to clear his eyes.
