I don't mean to be the negative one here..... BUT why would you get a dog where you can't have him? What happens if someone finds out he is there? Then the poor thing has to go to 'another' new home. I am sorry I just think this was an irresponsible thing to do. Not to mention the poor dog has to stay inside all the time. Dogs need fresh air and room to run. I also noticed you are getting rid of your rats cause you got a new dog. Will you get rid of your dog when the next pet comes along?
Sorry if this is taken the wrong way but I don't understand how you can just replace pets. This is not the first time in your posts something like this happened.
