is my dog normal?

I didn't know what group to put this under.

So I have a German shepherd and husky mix pup... his name is Noa and he turned 1 about a month ago. Y'all.... he farts and the smell makes me want to pass out. Last night he farted like every 15 minutes from 9pm-12am. Just want to know how normal it is for dogs to fart, is it suppose to smell so bad or overall, when should I be concerned lol. His diet has not changed, we feed him the same food.. it just seems like it's starting to happen a lot now.

I still love him though lol enjoy this photo of him.. he lays like this with all his toys.
