Hi there, So my family got a new dog just over a month ago, she is a rescue from Romania and has been a street dog, so obviously she's had some problems but shes been a lot better since we've got her. However the past 2 or 3 days she's become really nasty when it comes to a certain corner of the living room. We've put all her toys away so she can't guard them, but now whenever my stepdad goes to sit on the sofa she tries to attack him. She's nearly 4 years old and has been spayed, but we're pretty sure shes had puppies at some point. I've seen a few things about phantom pregnancies, and it seems like it could be something like that, I've noticed she's been digging the carpet etc, but I really dont know. If anyone has any advice that would be great, we really don't know what to do, we don't feel safe around her at the moment and I really don't know what to do. Like I said she had changed really quickly and she was never viscous until a few days ago.... please help!
