You have gotten some really good advice here. Absolutely you need to establish pack order. I have a 1 year old bulldog, and he was the toughest pup I ever owned. Since you got yours a little later, maybe some behavior training was lax with the first owner, and you have to start from square one. The best advice I can give you is no matter how hard it is, try not to lose control. I did it once, I was at my limit, and it made Bogey worse! I vowed to never lose my cool again, and I haven't. In doing this, I found that his bad behavior goes away when he loses my attention. He still gets over excited at times, like when he is chasing his ball. He doesn't like to " give" - instead he would rather we tug it from him. That is fine for awhile, but then he gets over excited, and starts to jump up and bite at me if I have the toy. I immediately take the toy away and we are done playing. He calms right down. As a pup I tried the submission maneuver, and it made him NUTS! He responded the best to time out in his crate. But I never put him in yelling or meanly. It was a firm no, and placement in the crate. Door shut gently and we walked away. He did not come out if he whined or cried. Maybe one on one playtime without your other dog would help with tiring him out. Is he crated for long periods during the day? They can be really tough but consistency, patience, love and gentle firmness will gain his trust in you and you will have a great dog! Good luck and keep us posted!
