I saw the movie when i was around 4 (2004-2005) and it was on regular television(in english). I was too young to know how to look for the title so i just remember seeing dogs on an assembly line type conveyor belt going into a big silver machine and coming out singular hot dogs, while some main characters (3-4) came up to rescue them. Due to how young i was when i saw it i dont have many leads because it could have been a movie or an episode of a tv show, and at this point im working to try and see if somehow i made it up because no one knows what im talking about when i bring it up. I do distinctly remember it being in flat 2d grungy-ish colored animation that could be from the 90s-80s, but it also could have been the real early 2000s.
