I have 2 austrailan shepards they are both 6 years old, I recently bought a pit. she is now 4 months old. by far and I know I have said this over and over she is the best dog I have had (pit) she being a puppy is sharper at learning things the dog was sitting at 7 weeks old, walking on a leash and now knows stay at 4 months, she is very loyal to me, and hasn't left my side, I did alot of research on the breed before purchasing her, and if you listen to the hype about how bad they are then you are missing out on a good thing..if you have the time and the patience, which is what you will need for any dog, then you will be pleased with the outcome...of course do research on the breeder as well, as there are may puppy mills just like with any breed.,
