The dog who adopted us....

Last weekend we had a few people over and a dog came up to one of our guests and he pet her and she hasn't left our house since. She looks like she is a pure breed Rottweiler. she has a pink collar but when we first saw her she didn't look like she had been fed in a while. She also looks like it wasn't too long ago that she had puppies. Its seems like maybe someone left her behind when they moved or dropped her off. I have gotten kind of attached to her, we named her Ginger. The problem is we can't keep her no matter what, soon our land lord is going to try and get home owners insurance on the trailer and they won't be able to with a rottweiler living here and we will be moving into married housing on campus as soon as we get married and I doubt we will be able to have her there. She is a sweet dog, I hate to have to let her go, but we are looking for a good home for her. We don't know her history, but she is gaining weight now we have been feeding her like crazy! Well I am attaching some pictures. I am going to miss her :(
