The city

This isn't a huge city, but it's not exactly tiny either. There's plenty of places to roam in this city, plenty of places to get food easily. Lots of places to cause trouble too, especially with all the humans walking around everywhere during the day. There are tall buildings with more than ten floors and then there are tiny buildings, there's also plenty of stores that a dog could easily attempt to steal something from. But there is also the dog catchers to watch out for, they're not exactly nice people and if they catch you then you'll definitely need saving from the pound.
