Hard to believe they grow so fast! I got Jax in Jan. '14. He was advertised on craigslist. I know that's not the first place to look for a dog, but I found it odd that someone would be getting rid of a 6 week old BM puppy on there. I decided to take a look at him and found out that the breeders were going to leave him on the side of the road because he was the runt of the litter and they never expected to have puppies in the first place. The guy that placed the CL add took him from the breeders but couldn't keep him. This little guy was waiting for me in the front yard as I walked up to see him. He never left my side after that. Even though he has no papers, I took him home and amazingly...for free!!! So far he has been the best dog I've had. Listens on command, no chewing, so laid back and easy going. I keep wondering if all Bullmastiffs are this way or did I just get very lucky!!!
