hi
i have a 9 month old american bulldog (ruby). i have grown up with large dogs in the family and there have never been any problems.my own dog however takes overexcitement to the next level. she jumps p whenever anyone walks into the house, and refuses to stop, she bites, not with aggression but as play again she will not stop when instructed. i have a young child and other children visit regularly including a baby, i cannot have ruby in the room when children are around as she is too bouncy, and often tries to lay on top of the children when they are sat down, also i am worried one of them will get hurt if she becomes too excited.
i ahev tried reward based training, i have tried 'timeout' sessions where i put her in the yard till she calms then she is allowed back in the house.
she followes basic commands such as 'sit' 'lay down' 'down' 'bed' and 'out'. other than those she refuses to listen to us.
anytime we try to discipline she thinks we are playing and the whole issue os excitement begins again.
also she pulls too much when on walks, she will ot calm down no matter whet we try!!

i could use some tips as to what to do with her as i cannot keep her locked away, as she is a part of the family! please help!!!
