I have a Fila pup who is now 6 mths. I would suggest lots of training with the proper trainer. I would find someone first who has a proven record with this type of breed or similar. Our pup is wonderful and we spend lots of time with her. I take her out daily to socialize at my office where she still will not cozy up with any stranger. I'm ok with this because we also have a happy Jack at home. The only problem is everyone wants to pat her because she is so cute. When we first got her we noticed how funny her movements were. She is very cat like in her movements. I wanted to ask the breeder what kind of cat he had breed in the line... My 14 year old has special needs and is a bit abusive at times. The pup is extremely tolerant of him. He hit her in the head tonight and it didn't even phase her one bit. She came back to him wagging her tail and bowing down to him to play. She sleeps alot and seems lazy sometimes but I realize how much she is growing. At 8 weeks she was the runt at 9lbs and at 6mths she is now 60lbs. She was housebroken in about 2 weeks. We just kept on her. She sleeps next to my bed and doesn't get up until I do. The best puppy ever. She has been a wonderful addition to our family. Lots of work!!!! I feel they are worth the work if you have the time. Not your average beast!!!!
