I have a Neapolitan Mastiff Cane Corso mix she is 11 months old 105 lb he is not getting along with my male dog we have tried several different tactics to see if she will get along with him but at this point I just can't do anything else she needs to be in a home that has no other animals in it she is a very loving girl for sure she knows some commands but at this point she is either in her cage or outside when she doesn't really do good outside she needs a fenced in yard I got her from breeders that I feel they did the whole braiding wrongly I got her at 7 weeks old she was never Ray's wrongly she was raised right just out of nowhere she started attacking my male dog and we've had him for a few years and he's the sweetest dog ever and we can't keep putting him through stress like this but like I said she is a wonderful dog just needs someone that has no other animals inside the home she is up-to-date on her shots she will need her third round puppy shots and then after that it will be every year
