I have a black lab and a yellow lab. About a 1/2 hour after they each finish a rawhide chew, the farting contest begins. And they are BAD ones too!
I hear ya, room clearing, my two chocs to the same thing. The funny part is when they fart and look at you like you did it while giving you that classic head tilt.
A couple of times, when my dog had farted particularly loudly, he turned around and growled at his rear.
He’s usually gassiest in the early morning, when we drive to the jogging track; I learned very quickly to drive with all the windows down!
