Oh absolutely! I tell anyone who wants to use ANY Lego media to help out the breed to go right ahead - no need to ask
Its such a shame they're banned over there.. Are you in Australia? I've heard a rumor that the breed ban there goes as far as to automatically seize and euthanize any pittie or pittie X, whether its done anything wrong or not (but gosh I hope that's not true!)
We have problems here too.. A couple nearby cities are considering implementing BSL. I myself turned down a good sized scholarship to my school of choice, all because the province where it's located has a strict pit bull ban and doesn't allow any to enter the province.. Sucks. BUT.. The rescue group that my boss helps run (Hugabull) has done something pretty cool to help raise awareness. They rented out a couple theatres and are showing the documentary called "Beyond the Myth" to the public these next two weekends. They also put aside tickets and invited city counsel members from various nearby municipalities, as well as news reporters, writers for dog magazines, vets and animal behaviour experts to come watch the documentary and stay for a panel discussion afterwards. Its sort of a cool way to raise awareness and get people to look past all of the hype.. AND most importantly, to educate thoe who are MAKING these laws, yet have little to no knowledge or experience with these dogs. It should be pretty fun, I'm going next weekend
