HI there everyone I own 2 english bulldogs one female and one male both are fixed.The one that I need help with is my male,he just turned 2.When I got him I didnt find anything wrong with him but now he is so nevous example,when he is in his creat and its time to let him out he doesnt even give you time to open door just runs right out,also when its time to go in he hides or runs upstairs not only with the create its even going for walks he pulls on leash and just wants to run.I take them both out every day and even take him beside me on a bike ride i thought maybe he just has alot of energy to burn but when he gets home he acts the same way.He is very friendly with other dogs and all people of all ages and listens very well sit stay lay down off leash when he is called comes right to me and sits any way can anyone give me some advice thanks
