I hate it when I open threads like these because then I usually have to say something. So, here goes. If Roxy isn't allowed inside like your other dog, then she should be rehomed. Dogs are very social animals and hate being alone. I was at animal control the other day and saw a dog shutting down because of it's situation. She was just staring into space, not even noticing me as I went by. As soon as I started talking to her, it's like she tried so hard to get through the fence to me. It broke my heart. The point I'm making is how can you do this to a dog on a daily basis? No wonder she looks happy to see you, as she's often just watching you inside your house. If you just had Roxy and your mom said no dogs in the house, it would be different. I think this situation is highly unfair for poor Roxy. And you can leave here if you want but it won't change the facts or the situation. Animals are a huge responsibility and if you're not prepared to accept that totally, then you need to wait until you can.
