Half the point of having a dog is to have someone to blame your own farts on.
I have heard a corgi fart exactly once (had to listen closely), never smelt one. If your corgi has bad gas, maybe a change of diet should be considered.
Twinkie is notorious for pooting. She is the first dog I have had that you could hear them! She really likes fruits and vegis and she only has bad gas when we have been letting her indulge. We also hypothesize that because of their tail-lessnes, cogis don't have the dampening effect that tailed dogs do. :O)
What food do you have him on? Oliver is on Purina puppy chow because that is what he was on when he got him, but he has the worst farts ever!! My dad has a black lab, and Oliver actually outdoes her! He thinks it's funny to sit on your lap and fart, then run away. However, we can always tell when daddy farts, as Oliver runs to 'sniff' out the situation!
Domino has nasty toots when she needs to potty. For some reason she doesn't tell us she needs to go out, she just doesn't do anything until we take her out. We try and walk her frequently, especially after she's been pinned by herself for long periods.
One night she was in bed with us and we kept blaming each other for it until we finally heard her do it, OMG it was loud and stinky! lol.
oh yeah, ein has smelly dog farts. he usually has them when he has 1 too many treats or he needs to go out. my hubby finally smelled one the other day and he totally freaked out. lol. he was like, "oh my god! ein! that was horrible!" lol. the worst was when he farted in the car. me and baby addie had to roll down the windows!!!
Norman had really stinky farts and his poops were never quite solid so the vet put him on low residue food and it works well. He rarely has the stinky farts anymore and his poops are now solid.
