Hi, I have a little issue, Josefina was an orphan (dumped at the AC at 4 weeks) the problem is that she at almost 2 yrs old (October 1st is her b day) but she still acts like a bothersome adolescent puppy towards other dogs; she will rub against them & if they tell her off she then lays down & stares at them & will otherwise be bothersome until the other dog retaliates & tells her to shove off, then she becomes combative which she doesn't do with buddy agree male) but she did try to retaliate back with Izze but Izze was very well socialized with many dogs & knew how to handle her if she tried to get combative without hurting her physically (she was a very caring dog deep down & never did things 'just to hurt') but she seems to be worse with other females & dogs smaller then her, why is this?
