We got Rogue almost 7 months ago as a rescue and she has been lovely. She has always been a little lead reactive, but over the last few weeks she has become hyper vigilant. Over the last week or so she has shown signs of aggressive anxiety at home - mainly towards Jasper - our other dog an 8 year old labradoodle. The longest this aggression has gone on for is 15 minutes and then Rogue is fine again, but Jasper is clearly nervous afterwards. I’m now beginning to get anxious about leaving them alone which I’m sure doesn’t help. They are only every by themselves 2.30pm-6pm between my husband leaving for work and me coming home and spend the entire time lying on the sofa together. I really want Rogue to have a happy life with us, but I’m worried that the aggression will get worse. I have tried positive reinforcement training, but it doesn’t seem to be working as I hoped. I am thinking I need some behaviouralist help, but don’t know who to turn to to avoid being ripped of or leaving her more stressed. Has anyone any suggestions?
