i think any dog would be fine as long as you can keep an eye on them. i know i will have to keep an eye on my toy poodle romulus he will probably be the first to try to show he is the dominate one.... and more then likely he will pick on the bigger stronger dogs (pits) lol (he has a Napoleon disorder)

i would be willing to hold it at my place i got a pretty large fenced in yard w/ a big deck + bbq grill.
