Hell yes shih tzu are straight retarded and pussies. My wife has one now. I've seen some dumbass dogs of every breed. I used to work at a vets office in the kennel section. Dobermans, on average, were the most well behaved. German shepards, rotty, and boxers did well too. At least in terms of not shitting all over their pen, barking non stop, spilling food and water, basically just not fucking spazzing out. Of course any dog can be trained, but i think some are just always going to be dumb. I think pits are pretty cool, they just seem like they could end up being a huge liability.
