I do not bias against aggressive dog breeds but I don't like aggressive dogs. I'd like to keep all my pets safe and that would make it that much harder. I prefer small to medium dogs since I am not a very strong person, I have limited control over large or giant dogs. Depending on said large dogs demeanor though, it would not be a problem!

My apartment complex has a nice lawn area in the middle of the community, the other tenants dogs are occasionally out there as well, they are required to wear a leash in this area at all times but it's great for quick potty breaks, short walks and new doggie friends(if you're ok with that of course). I can also take them for longer walks around town or I am also nearby Crystal Lake.
