Because of our current living situation, we have a 8 year old female boader collie living with our 5 year old ragdoll. Our cat was sick, so we had to bring her over to where we are living. The dog had not noticed her up until this last week since she has been in our large bedroom seperate from her. Now she is sniffing around the door and wanting in the room. What can we do at this point to not have world war 3 and not get my cat torn apart. Im not sure if that would happen, since the dog is very loving and docile, but im afraid at this point, and not sure what to do? I want them to be around eachother, does anyone have any suggestions on how to go about this??
