We have an olde standard english bulldog that has a very nasty disposition at times, I thought they were supposed to be good with children and docile. Bella is almost 8 months old and we have had her since she was 8 weeks old. She doesn’t like children at all. We have a 10 y/o son and a 16 y/0 son who are calm and very good with animals. Bella tolerates the 16 y/0 but is so mean to my 10 y/0. If will tries to sit anywhere in living room with us she will immediately go sit practically right on him and start very aggressively trying to bite him. She also has started humping him. Please help. We had her spayed about 2 weeks ago. She has a short fuse with everyone except for me. U can’t play with her at all as she becomes very violent and goes straight to biting really hard and growling. Then she will run like a maniac all over house jumping on all furniture sliding into walls it’s ridiculous. We don’t want to get rid of her but something has to give please help.
