Hi, I had an experience with a English Mastiff that we purchased from what is know as a back yard breeder. I dont think that he intent was to unleash aggresive animals just he loved his dogs didnt know really what he was doing and made money doing it. We paid 1500 for him back in 2005. I still have trouble coping with the whole situation. We did take him to puppy school. I invested all of my time and affection on this male dog (Ty). I was definately the pack leader and his favorite of the family. Early on I noticed he nipped me once because he was experiencing pain at around 5 months old, growth. We got him medication for that. I tried to comfort him then and he nipped me. That was first. It progressed from there. I have to admit that we led a rather restricted social life so I fault myself for that as far as maybe contributing to his fear aggression. We lived in a rural area with not a lot of human contact. One day the UPS guy came to the front door. Not an everyday occurance. He was with me on the second floor. He was going nuts so I reached for his collar to put him behind me and he turned and bit me good. I had to go to the hospital, no stitches. We had to involve the animal control officer, who was very helpful and sympathetic. He advised us to put the dog down. We did. Honestly at that point I was afraid of him. We have a ten year old daughter. I dont want to even think about it. I still cannot forgive myself. I still wonder what went wrong.
I'm sorry you went through that. It could have been a number of factors that contributed to the problem, poor breeding, pooor initial socialization, poor socialization after bringing him home..etc. But you cannot have a dog that bites around, period. You made the correct decision, espeically with children in the house.
I am very sorry that you made the choice to destroy the dog but also understand your fear for safety of you and your family. I have a learned that with the 2yr old male and the 12 mo old female that discipline starts early and it involves the entire family. We have a modern family that ranges between 46 and 7 years and everyone is involved with the two dogs. The dogs must learn respect and love at the time they step into your home. My 2 yr old has definitely had a behavior issue lately that we are working currently on and he is having some special handling and training for a while as he is growing into his adulthood and needs a little coaching right now. They are wonderful pets and are very good guard dogs but can be very territorial. I would recommend this breed to anyone that can control the dog and allow him to know his position within the family. Great temperament as long as they are trained.
