Hi there! I am new to this forum! I have a (beautiful!) 4 month old, 46lb Cane Corso/Rottweiler mix pup named Bella (her father is full Corso and mother is a mix of the 2). I have had her since she was 8 weeks old and she is very intelligent and sweet. I have been taking her to "puppy parties" (a puppy socialization 'class' at my local vet), as well as doggy daycare once or twice a week to socialize her with other dogs and people. I try to take her as many new places as possible. She has completed Puppy Obedience classes and will be starting the next set when she is 6 months old. She has always been alittle timid of men and that doesn't seem to be fading even with socialization. She is absolutely fine with women and children, but she barks at any men she sees (even when I take her to my parent's house, she will be fine with my father after a few minutes, but if he goes outside and comes back in she will go crazy barking at him again. She has never attempted to bite, and when he (or any other male) comes over to her she usually stops barking and becomes almost submissive and trys to stay as close to me as possible. Also, she plays great with other dogs (was very timid of new dogs at first as well, but has come around ALOT since taking her to puppy parties and doggy daycare and loves to play with them now) however I've noticed (as well as the staff at the daycare) that when I come to pick her up to take her home, when other dogs jump on me she will growl and bark at them. The staff said she doesn't do that at all when I'm not there, and she's fine with them as long as they aren't around me. I have 2 other dogs besides her and she doesn't mind when I give them attention etc. (well..she might try to weasel herself in to get some love too haha) but never shows aggression with them about it. Any suggestions would be greatly appreciated! Thanks!
