Haiden - next time you incounter a stuck animal or tourist or whatever - you do not need to coax the pet or anything else or use moveobjects on - simply go in edit town, click on the household and evict them to the clipboard - then replace them back in their house. It has two big advantages - it unsticks the sims and resets the lot so if anything has been corrupted by the route fail error, it gets reset and your lot will be like new. Plus you don't have to play all those households.
Now if you have what looks like serious problems going on in a neighborhood and you can't find all the sources or don't want to look - here's a real simple fix - bring up the cheat bar and type
resetsim *
makesure you do not forget the asterisk, and this will reset the entire hood and get tourists and stuck sims out of their predicament and all back home. Unfortunately if your sims -the ones you are playing are at work or school they will be sent home of course - so I generally try to only do that in the middle of the night - 3 am is a good time for almost all sims - but if it needs to be done during the daytime, just go back into your own household and click each sim to send them back to work or school if missing it will create problems. For some sims they get a bad mood - the achievers and ambitious types if they miss work or school. But they will get over it.
